Exercise 9 Review Sheet Lab Manual Human Anatomy
Raised area on lateral surface of humerus to which deltoid muscle attaches
Bones of the shoulder girdle
Sapulpa and clavicle
Radius and ulna
Scapular region to which the clavicle connects
Shoulder girdle bone that is unattached to the axial skeleton
Shoulder girdle bone that articulates with and transmits forces to the bony thorax
Depression in the Scapular that articulates with the humerus
Process above the glenoid cavity that permits muscle attachment
Distal Cordele of the humerus that articulates with the ulna
Medial bone of the forearm in anatomical position
Rounded knob on the humerus; adjoins the radius
Anterior depression, superior to the trachea, that 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 knuckles
Bones that articulate with the clavicle
Scapular and sternum
How is the arm held clear of the widest dimension of the thoracic cage?
Clavicle serves as an anterior base or strut to hold the arm away from the top of the thorax
What is the total number of phalanges in the hand?
What is the total number of carpal in the wrist?
Name the carpals (medial to lateral) in the proximal row.
prisform - triquetral - lunate - scaphoid
Name the carpal (medial to lateral) in the distal row.
trapezium - trapezoid - capitate - hamate
Descriptive terms for the pectoral girdle
1. Flexibility most important
3. Insecure axial and limb attachments
Descriptive terms for the pelvic girdle
2. Secure axial and limb attachments
3. Weight-bearing most important
What organs are protected, at least in part, by the pelvic girdle?
Uterus, urinary bladder, rectum, small intestine, reproductive organs
Distinguish between the true pelvis and the false pelvise
True pelvis - Small bowl-like shape containing the urinary bladder and sexual organs
False pelvis - Area between alla (wings of pelvis) - contains some abdominal organs
Difference between male and female pelvis
Female pelvis: further apart than males, scrum is wider, shorter, and less curved than males, pelvic inlet is wider, oval from side-to-side
Deduce why the pelvic bones of a four-legged animal such as the cat or pig are much less massive than those of the human.
Pelvic bones of two-legged animals have to carry more weight (divided by 2)
Four-legged animals divides it's weight over four legs
A person instinctively curls over his abdominal area in times of danger. Why?
To present a smaller target
To protect internal organs and genitalia
For what anatomical reason do many women appear to be slightly knock-kneed?
Women have wider pelvises than men and the angle of the hips turn the legs slightly inward.
How might the anatomical arrangement of the hips contribute to knee injuries in female athletes?
Can be more prone to knee related injuries due to high intensity knee landing or impact since the knee is already in a weak position
What does fallen arches mean?
Breaking down of the longitudinal or traverse arch of the foot
________, ________, and ________ fuse to form the coxal bone
Ilium, Ischium, and pubis
"Sit-down" bone of the coxal bone
Point where the coxal bones join anteriorly
Superiormost margin of the coal 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 the knee joing
Femur, tibia, patella
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
_____ and _____ : sites of muscle attachment on the proximal femur
Gluteal tuberosity and Greater and lesser trochanters
Tarsal bone that "sits" on the calcaneus
Weight-bearing bone of the leg
Tarsal bone that articulates with the tibia
