Appendicular Skeleton Anatomy

Appendicular Skeleton

• The clavicle is also known as the collarbone.
• The trochlea and capitulum are distal portions of the humerus.
• The human hand has greater dexterity than any animal forepaw because of the freely movable thumb joint.
• The ulna articulates proximally with the humerus.
• Metacarpal bones form the framework of the hand.
• The pisiform bone is located in the wrist.
• The false pelvis is above the pelvic inlet and bordered by muscle in the front, and bone along the sides and back.
• The anterior of the pelvic girdle is formed by the pubis.
• During childbirth, a baby passes through the pelvic outlet plane.
• The femur is the longest and heaviest bone in the body.
• A fractured patella would cause discomfort in the knee.
• The scaphoid is not a tarsal bone.
• The statement that the coccyx is less flexible in the male is not always true.
• From proximal to distal, the bones of the upper extremity are the humerus, radius, carpals, and metacarpals.
• From proximal to distal, the bones of the lower extremity are the femur, tibia, tarsals, and metatarsals.
• After age 50, bone density decreases slowly due to a shift in remodeling activity.
• Skeletal variations may be caused by an inadequate supply of calcium and vitamin D, mechanical stress and age.
