Anatomy Complex 3D/multiplanar structure, the pea-sized glans and shaft (variably hooded by the labia minora and curtained by the upper/anterior junction/commissure of the labia majora) the only distinctly visible surface element. There is also an internal portion of the shaft and a much bigger associated cluster of tissue, some clearly distinguishable anatomically/histologically (such as paired

Anatomy Most noticeable feature – odontoid process (derived from separation and fusion of body C1 with that of C2) rising from upper surface. Also large strong spinous process. C2 has complex articulation with atlas: Pivotal junction with odontoid process at 2 joints – front of odontoid with anterior arch C1, back of odontoid with transverse

Anatomy Medial end of clavicle (which is a long flat bone, elongated s-shape, convex at medial end, concave at lateral) articulates with manubrium of sternum. Clinical The only horizontal long bone (though ordinarily, no marrow), the clavicle acts as a strut, holding scapula in place and free to move on thoracic wall, which in turn

Anatomy Course A network of nerve fibers running from the spine to neck, axilla and forearm. It is divided into roots (C5, C6, C7, C8, T1), trunks (superior, middle and inferior), divisions (3 anterior and 3 posterior), cords (lateral, posterior and medial), and terminal branches (musculocutaneous, axillary, radial, median and ulnar nerves). Supply Responsible for

Anatomy Paired skin-covered mammary (milk-producing) gland (modified apocrine/sweat gland) ventral (in front of) pectoralis major muscle on thoracic/chest wall, levels ribs #2 to 6; can extend to axilla at side (sometimes as far as latissimus dorsi at back), up to clavicle, in/medial to sternum, made of adipose/glandular/connective/myoepithelial tissue, comprising 15-20 irregular lobes (each with 10-100

Anatomy Origin: Proximal part of the lateral supracondylar ridge of the humerus and adjacent intermuscular septum. Insertion: Lateral surface of the distal end of the radius. Key Relations: -One of the four muscles of the superficial posterior compartment of the forearm. -Lies anterior to the elbow joint. -Forms the lateral boundary of the cubital fossa.

Anatomy Course Continuation of the axillary artery after it has passed the inferior border of the teres minor muscle. It continues to proceeds downwards on the ventral surface of the arm until it reaches the cubital fossa, where it bifurcates in the radial and ulnar arteries. (Bifurcation sometimes occurs higher in the arm in some

Anatomy One of the three layers in living bone. Surrounded and protected by Compact Bone, Marrow is spongy and sits in the Medullary Cavity, the central cavity of bone shafts. Yellow and Red Bone Marrow is produced and stored. In infants, all of the marrow is Red. Red marrow produces red and white blood cells,

Anatomy Hollow distensible muscular organ, extra-peritoneal on pelvic floor behind pubic symphysis; 300-600 mls capacity; urine enters through ureteral openings 2-3 cms apart in posterior wall, is extruded through internal urethral orifice below (trigone the area thus bounded); dome, posterior surface covered with peritoneum; neck fixed by true ligaments of pelvis and fascia; body supported
