Muscular System, Posterior View

Description

Spanning from the occiput to the calcaneus, this posterior female figure layers superficial and deep back musculature, with trapezius and posterior deltoid capping the shoulder girdle and latissimus dorsi sweeping inferolaterally toward the thoracolumbar fascia and humerus. Along the midline, the erector spinae columns sit bilateral to the spinous processes, while the scapulae lie posterolateral to the rib cage with rhomboids and infraspinatus occupying the interscapular and scapular fossae. Distally, the triceps brachii forms the posterior arm mass above the olecranon, the gluteus maximus overlies gluteus medius at the lateral iliac crest, and the hamstrings and gastrocnemius continue inferiorly into the Achilles tendon. Color coding also traces posterior neurovascular courses, with segmental vessels and nerves traveling in parallel planes deep to the superficial muscle envelope. Posterior myology matters when you need reliable surface and deep landmarks for examination and procedure planning, because muscle borders often predict underlying neurovascular corridors. The interscapular region is a common site of referred pain and scapular dyskinesis, and this view clarifies how serratus anterior dysfunction alters scapular position against the thoracic wall even though the muscle itself sits on the anterior rib cage. It also frames typical compression or traction problems, such as irritation of dorsal rami in paraspinal muscle spasm and entrapment patterns around the quadrangular space affecting the axillary nerve and posterior circumflex humeral artery. Use this plate for posterior trunk and limb teaching in gross anatomy, kinesiology, and physical therapy curricula, and for editorial figures on back pain, shoulder mechanics, and gluteal and hamstring injury patterns, where readers need accurate relationships rather than isolated muscles. Suitable for clinical handouts that map palpation points, injection corridors, and surgical approaches that respect posterior muscular planes.
