The palmar fascia of the hand forms the muscular fascia overlying the thenar and hypothenar muscles. It bends medially with the palmar aponeurosis, proximally with the flexor retinaculum, and laterally with the dorsal fascia of the hand.
The thenar eminence is the mound formed at the base of the thumb on the palm of the hand by the intrinsic group of muscles of the thumb. [1] The skin overlying this region is the area stimulated when trying to elicit a palmomental reflex .
Comprehensive anatomy of wrist and hand and common sites of injury. Palmar and extensor neurovasculature. The origin, course, distribution, and anastomosis of the branches of the major vessels that supply/drain the hand (superficial and deep palmar arches) and fingers (digital branches).
7 maj 2024 · The palmar aponeurosis is a strong thickening of the central part of the deep fascia of the palm. It has little mobility and covers the underlying neurovascular structures, tendons and intrinsic muscles of the hand.
It is true that the 3 palmar interossei adduct and the 4 dorsal ones abduct the fingers from the midline of the hand; however, an understanding of the anatomy demonstrates how the insertions and actions of both sets of muscles synergize to provide the foundation for hand posture and hand function.
The palmar fascia shows continuity with the fascia antebrachii and the dorsal surface fascia of the hand. While the palmar fascia is thin in the thenar and hypothenar regions, it thickens in the center to form the fibrous palmaraponeurosis.
Palmar Aponeurosis (aponeurosis palmaris; palmar fascia) (Fig. 425). —The palmar aponeurosis invests the muscles of the palm, and consists of central, lateral, and medial portions. The central portion occupies the middle of the palm, is triangular in shape, and of great strength and thickness.
