| This study of the Harbour Porpoise Phocoena phocoena (Linnaeus, 1758) has been undertaken in order to find out whether differences in size and growth rate between the skulls of males and females could be demonstrated. Stuart & Morejohn (1980) have established this phenomenon in the population of the north-eastern Pacific. The material on which this study is based, consists of 76 skulls present in the collection of the Rijksmuseum van Natuurlijke Historie (RMNH), Leiden. They all belong to specimens stranded on the Dutch coast. In order to determine the age, of all these specimens the number of dentinal growth layer groups (GLG) in the teeth was counted. Thereupon 32 cranial characters were measured of each skull; these measurements were plotted against... |

| We investigated the somatic maturation of neonate rats treated during the suckling period with citalopram, a selective serotonin reuptake inhibitor. Groups with 6 male neonates were randomly assigned to different treatments 24 h after birth. Each litter was suckled by one of the dams until the 21st postnatal day. Body weight, head axis and tail length were measured daily from the 1st to the 21st postnatal day. Time of ear unfolding, auditory conduit opening, incisor eruption, and eye opening was determined. Pups received 5 mg (Cit5), 10 mg (Cit10) or 20 mg/kg (Cit20) citalopram sc, or saline (0.9% NaCl, w/v, sc). Compared to saline, body weight was lower (24.04%, P < 0.01) for Cit10 from the 10th to the 21st day and for Cit20 from the 6th to the 21st... |

| Some measurements in the mandibles and upper jaws of thirty West African Dwarf (WAD) goats without any apparent skeletal disorders were analysed. The length and height of the mandibles were 12.00 cm and 6.90 cm, respectively. The distance from the lateral alveolar root to the mental foramen, from the mental foramen to the caudal mandibular border were 1.56cm, 9.96cm, and 2.58cm respectively. The width and height of the mental foramen were 0.5 cm and 0.3 cm, respectively. These data are discussed with regard to their application to clinical manoeuvres around the head of the goat such as regional anesthesia during dental extraction |

| The study involved the measurements of some clinically important landmarks for regional anesthesia in the head of twenty five Red Sokoto goats. The length and maximum height of the mandibles were 12.7cm and 7.7cm respectively. The distance from the mandibular foramen to the base of the mandible was 3.0cm while the distance between the lateral alveolar root and mental foramen and from the facial tuberosity to the infra-orbital foramen was 1.8cm in both instances. The data was discussed with regard to its importance in proper tracking of some nerves in aid of regional anaesthetic procedures in the head of the Red Sokoto goat and was compared with our results reported for the West African Dwarf breed |

| The sex determination from human skulls can be made by means of morphologic and morphometric methods have been broadly studied. These methods contribute with objective data; however, they present interpopulational variability. The purpose of this article is to determine sexual dimorphism using lineal dimensions in a sample of human skulls collection belonging to the Universidade Federal de Sao Paulo (UNIFESP), calculating the discriminant function. To complete the selection approaches, 226 skulls were analyzed. Mensurements were carried out among the following reference points of the skull: right Eurion- left Eurion (Eu - Eu), Glabella-Opisthocranion (Gla - Op), Basion - Bregma (Ba-Br), Nasion - Prosthion (Na-Pr), Bizigomatic (Zi-Zi), Maximal width of the... |

| A divided infraorbital foramen is an important morphological feature in lion taxonomy and has previously been considered to occur only in the Asian lion, Panthera leo persica. Based on an examination of 498 lion skulls from museum collections in Europe and southern Africa, we report for the first time on the prevalence of the divided infraorbital foramen in African lions, as well as its occurrence in the tiger, P. tigris and the extinct Pleistocene European cave lion, P. leo spelaea. The higher frequency of this characteristic in Asian lions may have occurred after the lion colonised Asia, and can be considered an important morphological feature characterising this population. It is not clear whether recent anthropogenic population bottlenecks have... |

| Inadequate ossification of the interparietal region induces the appearance of interparietal and wormian bones, also associated with genetic factors. The formation of the interparietal bone depends on the separation of the intermediate segment from the lateral plate by the transverse occipital suture, which means that this bone is formed by the medial and lateral plates. Wormian interparietal bones or epactal bones are located within the interparietal region, being single or multiple, and are located in the upper central region of the interparietal region, the sutural bones, however, are formed from additional ossification centers that can occur in near sutures. The aim of this work was to macroscopically evaluated the presence of changes in the structure... |

| It is known that there exists close relationship between cranial capacity and size of the brain. Several studies have estimated the cranial capacity, which indirectly reflects the brain volume in different populations. The aim of this study was to estimate cranial capacity of a particular age group of population of Madhya Pradesh. This study was carried out on 400 healthy 20-25 year old (200 male and 200 female) individuals of Madhya Pradesh state of India, by using linear dimensions of head (Lee Pearson's formula). The mean cranial capacity and SD in males & females were 1380.52±94.63 cc and 1188.75±91.16 cc respectively. This study has shown a significant (p<0.05) difference between male and female population, being higher in males than in... |

| This study, based on a 48 Xisqueta skull samples, gives a statistical insight of the skull shape in this breed. Thirty eight measurements and eight indexes were recorded. The variance structure was done using a Principal Component Analysis (PCA). This was possible sequel to the application and permission of the covariance matrix. The mean length of the skulls was found to be 265.51±22.24 mm, with the width and cephalic index to the magnitude of 117.2 ± 6.89 mm and 44.69 ± 4.29 mm, respectively. The viscerocranium length was 143.07±9.74 mm thus indicating a similar portion with the neurocranium part of the skull (137.17 ± 6.25 mm). The orbit was slightly almond shaped. Variability was generally high within parameters but parameter variation was less in... |

| Knowledge about human skull asymmetry in normal dry specimens is useful as a parameter for medical and dentistry practice. Skull base was investigated with the objective to validate the method of indirect measurement with digital pictures and to evaluate the degree of asymmetry from human skull base in different ages. We analyzed 176 normal identified human skulls, divided by age in the following groups: Fetuses, newborn, children and adults. Measures were taken from a central point: pharyngeal tubercle and 4 lateral points: foramen ovale, foramen spinosum, carotid canal and stylomastoid foramen using digital biometry after a comparative validation with directed method performed with caliper. Results were presented as asymmetry indexes and data were... |

| Piriform aperture and nasal bone contribute to the formation of the nose. Its morphology varies according to ethnic group and gender. The piriform apertures and nasal bones of 97 individuals were examined radiographically through Caldwell radiographic technique and the types of nasal bones were classified according to Hwang et al. (2005). The width, height and area of piriform aperture were measured to demonstrate the difference according to gender. Statistical analysis was performed from the Student t test and analysis of variance (ANOVA). The most frequent type of nasal bone was A, and D was the most uncommon in both genders. In the Student t test significant differences between genders, height, width and area of the piriform aperture were obtained and... |

| In this study we tested the hypothesis that diagnostic performance of the morphological indicators for sexual dimorphism are reduced as they are applied in skull and mandibles of older subjects. We used 275 adult human skulls, 250 of these with mandible, all subjects with sex and age registry. Sixteen classic morphological indicators of sexual dimorphism were evaluated, this information was compared with the registry and results noted in terms of precision. The best general performance of morphological indicators of sexual dimorphism were recorded in the 31 - 40 and 61 - 70 years, age range groups. Lowest precision ws recorded in the group corresponding to subjects between 21 30 years. Our results do not support the proposed hypothesis and suggest a... |

| Foramen ovale and spinosum are important foramina of the greater wing of the sphenoid. Normal variations in their shapes and sizes are quite common and widely studied. In the present study, conducted in the Department of Anatomy of School of Medical Sciences, Universiti Sains Malaysia, 25 dried human skulls were examined for anatomic variations of the foramina of the greater wing of the sphenoid. During the study, we noticed anatomic variations of the foramen ovale and spinosum. In one skull, there was an abnormally large and irregular foramen ovale which was confluent with the foramen spinosum. In the second skull, the foramen spinosum was absent on the left side and in the 3rd skull it was duplicated on the right side. These variations are very rare and... |
