Lecture Exam 3 - Appendicular Skeleton

pectoral girdle
the appendicular bones that support the arm bones
pelvic girdle
the appendicular bones that support the lower limb bones
acromion process
extension of the scapula that articulates with the clavicle
coracoid process
anterior, superior projection of the scapula that does not articulate with another bone, but serves as a point for muscles to attach to
glenoid cavity
the smooth depression in the lateral surface of the scapula that receives the head of the humerus to form the shoulder joint
brachial bone
greater tubercle
large process opposite the head of humerus
deltoid tuberosity
a small projection on the lateral surface of the humerus mid-way between the proximal and distal ends
a round knob-like process on the lateral distal humerus; the radius articulates at this surface
a spool-shaped structure on the humerus around which the ulna rotates
coronoid process
this is the name of a process on both the mandible and on the ulna
olecranon fossa
depression on the posterior surface of the humerus accepting projections from the proximal end of the ulna as the antebrachium extends
medial epicondyle
raised area on the distal and medial side of the humerus
lateral epicondyle
raised area next to the lateral condyle of the femur
the lateral antebrachial bone
interosseous membrane
membrane between the tibia and fibula, and between the radius and ulna
styloid process
sharp projection from the distal medial end of the ulna
radial tuberosity
small projection that is medial and inferior to the neck of the radius; attachment site for biceps brachii muscle
the medial antebrachial bone
olecranon process
forms the bony prominence of the elbow
trochlear notch
half-moon indentation of the ulna; articulates with humerus
carpal bones
bones of the wrist
bone of the hand between the wrist and each finger
finger and toe bones
os coxae
the ilium, ischium, and pubis fuse to form this pelvic bone; 2 of these join the sacrum and coccyx to form the bony pelvis
the superior fetal and childhood bone that fuses with two other early bones to form the os coxae
iliac crest
superior rim of the os coxae
inferior and posterior region of the os coxae - an individual bone throughout childhood that fuses with two others to form the os coxae in adults
ischial tuberosity
inferior blunt projection from ischium that hamstring muscles attach to - you sit on this
ischial spine
sharp posterior projection, superior to ischial tuberosity
greater sciatic notch
large indentation on the posterior aspect of the os coxae, between the posterior inferior spine and the ischial spine
the most anterior of the 3 childhood bones that fuse to form the os coxae
obturator foramen
the largest hole in your skeleton; located on the os coxae
the cup-shaped depression in the os coxae into which the head of the femur fits to form a ball-and-socket joint
false pelvis
portion of the pelvis found superior to the pelvic brim; that portion of the abdominal cavity partly protected by the ilium region of the ossa coxae
true pelvis
pelvic cavity found inferior to the pelvic brim; protects the bladder and some reproductive organs
thigh bone
greater trochanter
the more superiorly located of the two large projections on the proximal end of the femur; used for muscle attachment
intercondylar fossa
a shallow depression between the condyles at the distal end of the femur
largest sesamoid bone in the body
intercondylar emminence
projection between the condyles at the proximal end of the tibia, helps stabilize against side to to side movement
tibial tuberosity
bone region where the patellar ligament attaches to the tibia
medial malleolus
projection from the distal end of the tibia; easy to palpate just superior to the tarsus
lateral malleolus
projection from the distal end of the fibula; easy to palpate just superior to the tarsus
anatomical region between the metatarsus and the leg
largest tarsal bone; makes up your heel
a bone that articulates with the tibia and fibula
found in the glenoid cavity
acromion process
the most superior part of the scapula
subscapular fossa
found on the anterior surface of the scapula
infraspinous fossa
found on the posterior surface of the scapula inferior to the scapular spine
supraspinous fossa
found on the posterior surface of the scapula superior to the scapular spine
of the 3 fetal bones that fuse to form the os coxae, this is the only one that does not make up part of the obturator foramen
