A Study on the Variations in the Formation of the Trunks of Brachial Plexus International Journal of Morphology
Shetty,Surekha D; Nayak B,Satheesha; Madahv,Venu; Braganza,Cilwyn Shalitha; Somayaji,S. N.
Brachial plexus shows several variations in its formation and branching pattern. Variations in the formation of the trunks are very rare. We studied 44 dissected specimens specifically for variations in the formation of the trunks of the brachial plexus. 5 cadavers (11.3%) showed variations in the formation of the trunks. All the variations were unilateral. In one cadaver (2.27%), the middle trunk was formed by union of C7 and C8 roots and lower trunk was formed by T1 root. Upper and middle trunks were fused with each other in one specimen (2.27%). In 3 specimen (6.81%), the C5 root pierced scalenus anterior before joining C6 to form the upper trunk. Knowledge of its variations is of importance to orthopedic surgeons, neurologists and anesthesiologists.

A Variation of Phrenic Nerve: Case Report and Review International Journal of Morphology
Prakash,; Prabhu,Latha V; Kumar,Jwalaram; Madhyastha,Sampath; Singh,Gajendra.
During routine dissection in the Department of Anatomy following anatomical variations of phrenic nerve were observed on right side in the neck region of a middle aged cadaver. The phrenic nerve in its early course close to its origin was giving a communicating branch to C5 root of brachial plexus and at the level of the root of neck just before entering the thorax, the phrenic nerve was placed anterior to the subclavian vein. This unique case of phrenic nerve variation gains tremendous importance in context of subclavian vein cannulation, implanted venous access portals, and supraclavicular nerve block for regional anesthesia

Face and Neck Development in Vertebrates International Journal of Morphology
Meruane,Manuel; Smok,Carolina; Rojas,Mariana.
The embryonic development of the facial area, neck, nasal, oral and pharyngeal cavities with glands, involves growth and fusion of multi-dimensional processes. There is involvement of elements from the embryo-derived local 3 layers cells further neural crest derived cells from the neighbors rhombomeres. The neural crest cells are involved in the formation of local skeleton, among other structures. The study of evolution from jawless vertebrates shows us how Hox genes are expressed in different species, and how this determines the formation of different structures. The following review contemplate some morphological, molecular and evolutionary basis of facial and neck development, with emphasis on mammals with an epilogue concerning to the face and neck...

Functional morphology of a highly specialised pivot joint in the cranio-cervical complex of the minute lizard Ablepharus kitaibelii in relation to feeding ecology and behaviour Naturalis
Natchev, N.; Tzankov, N.; Vergilov, V.; Kummer, S.; Handschuh, S..
The snake-eyed skink Ablepharus kitaibelii is one of the smallest European lizards, but despite its minute size it is able to feed on comparatively large prey. Here we investigate the diet of A. kitaibelii and the mechanisms that allow the skink to overpower relatively large and even noxious prey. High-speed cinematography showed that A. kitaibelii uses a series of shaking and battering movements to immobilise and kill prey prior to swallowing. During this process, the skinks rises up on the hind limbs and then whacks the prey sidewise on the substrate by twisting the trunk, neck and head laterally. Our analysis showed that the shaking kinematics is very uniform among the investigated specimens. The morphological investigation of the cranio-cervical system...

Subjective measurements of fat cover and kidney knob and channel fat for predicting shoulder, neck and flank plus breast tissue composition of Blanca Celtibérica kids. IPB - Escola Superior Agrária
Delfa, R.; Joy, M.; Panea, B.; Jiménez Badillo, M.R.; Teixeira, A..
CCW, the assess of FC on two scores (1-5) and (1-15) and the assess of KKCF amount on two scores (1-3) and (1-9) were used as predictors of shoulder, neck and flank plus breast tissue composition of 31 Blanca Celtibérica kids, with an average CCW of 6,9± 2,1 Kg. Proportionately 97, 91 and 92% of the variation in muscle weight of shoulder, neck and flank plus breast, respectively were accounted for by variation in CCW. The variation in CCW also explained 96, 49 and 86% of the variation of shoulder, neck and flank plus breast bone tissue composition. The inclusion in the prediction equation for neck bone weight of FC (1-15), increase the precision in 7% and reduced the RSD in 5,7%. Finally the variation in CCW and FC (1-15) explained 87, 76 and 90% of the...

The Levator Claviculae Muscle and Unilateral Third Head of the Sternocleidomastoid Muscle: Case Report International Journal of Morphology
Fazliogullari,Zeliha; Cicekcibasi,Aynur Emine; Unver Dogan,Nadire; Yilmaz,Mehmet Tugrul; Buyukmumcu,Mustafa; Ziylan,Taner.
A rare case of unilateral third head of sternocleidomastoid and an extra muscle levator claviculae were determined unilaterally in a 70-year-old male cadaver during the routine dissections. In the left neck side, it was observed that the sternocleidomastoid muscle also had a third part in addition to known sternal and clavicular heads and levator claviculae muscle which arose from the posterior tubercle of the transverse process of the 3rd cervical vertebra and attached to the posterior margin of the clavicle. An awareness of this variations may be important because of its close relationship with neurovascular structures during neck operations.
