Anatomy Course Anterior division of the fourth thoracic spinal nerve. Runs along the fourth intercostal space, below the superior rib until it ends as the anterior cutaneous branch which surfaces to supply the cutaneous skin. Along the way it gives off a lateral cutaneous branch that emerges superficially and splits into a posterior and anterior

Anatomy Course Anterior division of the first thoracic spinal nerve. Runs along the first intercostal space, below the superior rib until it ends as the anterior cutaneous branch which surfaces to supply the cutaneous skin. Rarely is a lateral cutaneous branch associated with this nerve. Supply Somatic motor innervation to the thoracic wall muscles, sensory

Motion The intercarpal joints are synovial ellipsoid or spheroidal joints. The term intercarpal joints refers to the joints between the proximal row of carpal bones, the joints between the distal row of carpal bones and the complex midcarpal joint between the two rows.

Anatomy Origin: Medial two-thirds of infraspinous fossa of scapula and infraspinous fascia that covers the muscle. Insertion: Middle facet of greater tubercle of humerus. Key Relations: -The tendon of infraspinatus is sometimes separated from the capsule of the shoulder joint by a bursa, which may communicate with the joint cavity. -One of the four muscles
