Abstract

Introduction: Palmaris longus, one of the superficial flexor muscles of the anterior compartment of the forearm is the most variable muscle of the upper limb. Purpose: To note the variations of palmaris longus for tendon grafts. Methods: Forty formalin-fixed upper limb specimens of South Indian population were dissected to note the variations of Palmaris longus muscle. Results: Out of the forty upper limb specimens, two variants of the palmaris longus were noted. In one specimen, a reversed palmaris longus was noted. It had a long tendinous origin with a muscle belly and a short flat tendon at insertion. The tendon inserted partly into the flexor retinaculum and partly into palmar aponeurosis. In another specimen, apart from the normal palmaris longus muscle, an additional smaller muscle was noted. It was the Palmaris profundus. This muscle took origin in the form of a tendon from the middle of the shaft of the radius, continued as a muscle belly and then terminated as a tendon which later inserted into the flexor retinaculum, close to the tendon of palmaris longus muscle. At its insertion, the superficial palmar branch of radial artery hooked it. The anterior interosseous nerve supplied the Palmaris profundus. Conclusion: These variations are worthy to be noted for tendon grafts.

Abstract

Context : Facial artery is usually the main artery supplying the face. It gives three named branches on the face, the inferior labial, the superior labial and the lateral nasal and continues as the angular artery. Face is also supplied by the transverse facial artery and the arteries accompanying the cutaneous nerves. Aim: In the present study, variations of facial artery on face were observed. Settings & design: Department of Anatomy, Kasturba Medical College, Manipal. Material & method: The present study was performed on 38 males and 12 females' formalin-fixed hemi-faces. Diameter of facial artery was noted at two specific points using a fine microcaliper . Results: The variations were divided into 3 categories. Out of 38 male hemi-faces, 100% right and 78% left hemi-faces belonged to type I category; 22% left hemi-faces belonged to Type III category. Out of 12 female hemi-faces, 80% right and 80% left hemi-faces belonged to Type I category, 18% left hemi-faces belonged to Type II category and 20% right and 2% left hemi-faces belonged to Type III category. Premasseteric branch was observed in 4 hemi-faces; a duplex with a prominent lateral angular branch was observed in 4 hemi-faces and anenlarged transverse facial artery was seen in 2 hemi-faces. The diameter of facial artery at its origin and at the antero-inferior angle of masseter muscle was larger in males. Conclusion:This study shows that the variations in the branches and the diameter of the facial artery were relatively larger in males when compared to females. [ABSTRACT FROM AUTHOR]

Abstract

During routine dissection of the thoracic region of a 55-year old male cadaver, in the department of Anatomy, Kasturba Medical College, Manipal, various anomalies were noticed in the thoracic region. a) The arch of aorta gave rise to four branches, the right common carotid artery, left common carotid artery, left subclavian artery and a right subclavian artery. The origin of the right subclavian artery was to the left of the midline and in order to reach the right arm, the artery coursed behind both the trachea and oesophagus. b) Cervical rib was present on both the sides. c) Thoracic duct coursed on the same side without crossing to the left at the T5 vertebral level. d)Hemiazygos vein was underdeveloped.

14. Unilateral anatomical variation of the ansa cervicalis.

Author

Abstract

The ansa cervicalis is a loop of nerves that is usually formed by the union of ventral rami of spinal nerves C1, C2, and C3. It is located in the carotid triangle of the neck, lying superficial to the carotid sheath. During routine dissection, unilateral variation of the ansa cervicalis was observed. The superior root, arising from hypoglossal nerve, was initially bifurcated and later united to form a single superior root. IN addition, the inferior root consisted of fibres arising from the spinal accessory nerve, C1, C2 and C3 spinal nerves that joined separately. Fibres from the spinal accessory and C1 joined to form a single root. Thus, a 'triple form' of ansa cervicalis was observed. An interconnection was observed between the C2 and C3 fibres. Knowledge of such anatomical variations is important for surgery, clinical intervention or trauma involving the carotid triangle or the structures within or deep to this region.
