The Appendicular Skeleton Flashcards
Raised area on lateral surface of humerus to which deltoid muscle attaches
Bones of the shoulder girdle
Scapula and clavicle
Radius and ulna
Scapular region to which the clavicle connects
Shoulder girdle that articulates with and transmits forces to the bony thorax
Depression in the scapula that articulates with the humerus
Process above the glenoid cavity that permits muscle attachment
Distal condyle of the humerus that articulates with the ulna
Medial bone of forearm in anatomical position
Rounded knob of the humerus and adjoins the radius
Anterior depression that receives part of the ulna when the forearm is flexed
Forearm bone involved in formation of elbow joint
Heads of these bones form the knuckles
Bones that articular with the clavicle
Scapula and sternum
How is the arm held clear of the widest dimension of the thoracic cage
Clavicle serves as an anterior base to hold the arm away from the top of the thorax
Total number of phalanges in hand
Total number of carpals in the wrist
What organs are protected by the pelvic girdle?
Reproductive organs, urinary bladder, part of the large intestine
Distinguish between true and false pelvis.
False pelvis makes up the larger part of the pelvis. Superior. Supports abdominal viscera.
True pelvis is the inferior region, and the cavity is short and small-bowled shape that encases the urinary bladder and reproductive organs
For what anatomical reason do women appear to be slightly knock-kneed?
Women have wider pelvises than men. Angle of hips turn slightly inward, giving that appearance.
How might this anatomical arrangement contribute to knee injuries in women?
More prone to knee injuries such as ACL tears due to high stress/impact directly to knee
What does fallen arches mean?
Ligaments and tendons are weakened which allow the bones to fall. Causes appearance of flat feet.
What 3 bones fuse to form the coxal bone?
Ilium, ischium, and pubis
"Sit down" bone of the coxal bone
Point where coxal bones join anteriorly
Superiormost margin of the coxal bone
Deep socket in the coxal bone that receives the head of the thigh bone
Joint between axial skeleton and pelvic girdle
Longest, strongest bone in the body
Thin lateral leg bone
Heavy medial leg bone
Bones forming knee joint
Femur and tibia
Joint where the patellar ligaments arttaches
Medial ankle projection
Lateral ankle projection
Largest tarsal bone
Bones forming the instep of the foot
Opening in hip bone formed by the public and ischeal rami
Sites of muscle attachment on the proximal femur
Greater and lesser trochanters & gluteral tuberosity
Tarsal bone that sits on the calcaneous
Weight bearing bone of the leg
Tarsal bone that articulates with the tibia
