Palmar carpal branch of ulnar artery

From WikiMD's Wellness Encyclopedia

Palmar carpal branch of ulnar artery is a branch of the ulnar artery that supplies blood to the carpal bones of the hand. It is one of the many branches of the ulnar artery, which is itself a branch of the brachial artery.

Etymology[edit | edit source]

The term "palmar" comes from the Latin "palma", meaning "palm of the hand". "Carpal" is derived from the Greek "karpos", meaning "wrist". "Ulnar" refers to the ulna, one of the two bones of the forearm, and "artery" comes from the Latin "arteria", meaning "windpipe, artery".

Anatomy[edit | edit source]

The palmar carpal branch of ulnar artery arises from the ulnar artery in the distal part of the forearm. It travels towards the wrist, where it anastomoses (connects) with the palmar carpal branch of radial artery to form the palmar carpal arch. This arch supplies blood to the carpal bones and the structures in the palm of the hand.

Clinical significance[edit | edit source]

The palmar carpal branch of ulnar artery, like other arteries, can be affected by atherosclerosis, a condition where plaque builds up inside the arteries. This can lead to reduced blood flow to the hand, causing symptoms such as pain, numbness, and in severe cases, tissue death.
