Palmar

Palmar refers to the anatomical term of location that denotes something related to the palm (the flexor anterior/bottom surface) of the hand. It is the opposite of Dorsal, which refers to the back of the hand.

Anatomy

The palmar surface of the hand is the surface that one would use to high-five someone. It contains the Flexor muscles, which are responsible for bending the fingers and thumb, and is covered by thick skin which forms the Fingerprints.

Palmar Grasp Reflex

The Palmar Grasp Reflex is a primitive reflex found in infants of humans and most primates. When an object is placed in the infant's hand and strokes their palm, the fingers will close and they will grasp it. The grip is strong but unpredictable; though it may be able to support the child's weight, they may also release their grip suddenly and without warning. The reverse motion can be induced by stroking the back or side of the hand.

Palmar Fascia

The Palmar Fascia is a thin, triangular, radiated structure, situated upon the front of the hand, superficial to the tendons of the Flexor muscles. It protects the nerves and vessels that pass into the hand from anterior to it.

Palmar Erythema

Palmar Erythema is redness of the palms at the thenar and hypothenar eminences. It is a symptom of various diseases and conditions, including liver cirrhosis, rheumatoid arthritis, and pregnancy.
