raised area on lateral surface of humerus to which deltoid muscle attaches
along with the scapula, a bone in the shoulder girdle
along with the ulna, a forearm bone
scapular region to which the clavicle connects
shoulder girdle bone that is unattached to the axial skeleton
shoulder girdle bone that transmits force fromt he upper limb 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 on the humerus; adjoins the radius
anterior depression, superior to the trochlea, which receives part of the ulna when the forearm is flexed
forearm bone involved in formation of the elbow joint
heads of these bones form the knuckle
along with the sternum, bone that articulates with the clavicle
Why is the clavicle at risk to fracture when a person falls on his or her shoulder?
It is a slender, lightweight bone that withstands trauma poorly
Why is it generally no problem for hte arm to clear the widest dimension of the thoracic cage?
The clavicle acts as a strut to hold the glenoid cavity of the scapula (therefore the arm) laterally away from the narrowest dimension of the rib cage.
What is the total number of phalanges in the hand?
What is the total number of carpals in the wrist?
Name the carpals (medial to lateral) in the proximal row. Next name the carpals (medial to lateral) in the distal row.
pisiform, triagular (triquetrium), lunate, scaphoid; hamate, capitate, trapezoid, trapezium.
flexibility most important
nsecure axial and limb attachments
secure axial and limb attachments
weight-bearing most important
What organs are protected, at least in part, by the pelvic girdle?
uterus (female), bladder, small intestine, rectum
Why are the pelvic bones of a four-legged animal (like a cat or pig) much less massive than those of the human?
The pelvic girdle does not have to carry the entire weight of the trunk in the quadruped animal.
Distinguish between the true pelvis and the false pelvis
The true pelvis is the region inferior to the pelvic brim, which is encircled by bone. The false pelvis is the area medial to the flaring iliac bones and lies superior to the pelvic brim.
A person instinctively curls over his abdominal area in times of danger. Why?
Abdominal area organs recieve the least perotection from the skeletal system.
For what anatomical reason do many women appear to be slightly knock-kneed?
The pelvis is broader and the acetabula and ilia are more laterally positioned. thus, the femur runs downward to the knee more obliquely than in the male.
What does "fallen arches" mean?
A weakening of the tendons and ligaments supporting the arches of the foot.
inferoposterior "bone" of the coxal bone
point where the 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
point where the patellar ligament attaches
medial ankle projection
lateral ankle projection
largest tarsal bone
bones forming the instep of the foot
opening in hip bone formed by the pubic and ischial rami
tarsal bone that "sits" on the calcaneus
weight-bearing bone of the leg
tarsal bone that articulates with the tibia
