The teres minor lies inferior to the infraspinatus and superior to the teres major; all three muscles have a similar oblique orientation. In anatomical position, the long head of the triceps brachii muscle is oriented perpendicular to the teres minor and inferior to it. The teres minor is deep to the deltoid muscle. Function The triceps muscle is responsible for the extension of the elbow joint and straightening of the arm, and it also plays a significant role in the stability and strength of the shoulder. The triceps' position and function are critical for sustaining upper body strength and facilitating coordinated arm movements. Triceps Exercises The white matter contains descending and ascending tracts. The descending tracts transmit motor signals to the periphery and the ascending tracts transmit sensory signals to the brain. Thirty-one pairs of peripheral spinal nerves arise segmentally from the spinal cord and conduct autonomic, motor, sensory, and reflex signals between the. CNS. The triceps run along the humerus (the main bone of the upper arm) between the shoulder and the elbow. Along with the biceps, it enables extension and retraction of the forearm. The nerve root of C7 runs between vertebrae C6 and C7. Motor function includes: full shoulder movement (rotation, adduction and abduction) strong scapular stability. elbow extension - tricep (ability to straighten bent arm) strong wrist extension. moderate grasp (extensor digitorium muscle permits extension of digits, some finger flexor muscle 3 Branches in axilla. posterior cutaneous nerve of the arm. branch to long head of triceps. branch to medial head of triceps. Triangular interval. it then runs through the triangular interval with profunda brachii artery in posterior compartment between long head of triceps and humerus. Spiral groove. next it courses through the spiral groove wMmH.
