Which bone has the head located on the distal end?
Distal ulna. The distal head of the ulna is comprised of the articular circumference which articulates with the wrist bones and posteriorly, a bony projection known as the styloid process. Just above it on the medial aspect of the bone, the attachment of the pronator quadratus which runs between the radius and the ulna is positioned.
What does proximal end mean?
Specifically, “distal” or “caudal” is used to refer to the body and tail of the pancreas, and “proximal” (and presumably “cephalad”) refers to the end containing the head and uncinate process.
What is the difference between lateral and distal?
What is the difference between lateral and distal? Lateral – away from the midline of the body (example, the little toe is located at the lateral side of the foot). Distal – away from or farthest from the trunk or the point or origin of a part (example, the hand is located at the distal end of the forearm). Is the elbow proximal to the wrist?
What bone is distal to the femur?
The proximal end of the femur includes the:
- femoral head
- neck
- trochanters
- intertrochanteric crest
- intertrochanteric line
What is the end of long bones called?
epiphysisThe wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone.
What are the three parts of the long bone?
Long bones are longer than they are wide. They can be divided into three regions - epiphysis, metaphysis and the diaphysis. The epiphysis contains the spongy bone (also called cancellous), which in turn contains the red bone marrow that is responsible for synthesizing blood cells.
What is the proximal epiphysis of a long bone?
The proximal epiphysis is the end of the long bone closest to the center of the body. The distal epiphysis is located at the end of the long bone that is farther away from the center of the body.
What are parts of long bone?
A long bone is a bone that has a shaft and 2 ends and is longer than it is wide. Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line.
