Question 1

What Is the clavicle?

Answer 1

collar bone
slender doubly curved bone

Question 2

Where is the clavicle attached?

Answer 2

manubrium of the sternum medially and to the scapula laterally
- helps form the shoulder joint

Question 3

What is the scapula?

Answer 3

• shoulder blades
• triangular and called wings
• they flare when arms are moved poteriorly

Question 4

What are the two important processes of the scapula?

Answer 4

acromion
coracoid process

Question 5

what is acromion?

Answer 5

• the enlarged end of the spine of the scapula
• it connects with the clavicle laterally to form the acromioclavicular joint

Question 6

what is the coracoid process?

Answer 6

• points over the top of the shoulder
• anchors some of the muscles of the arm

Question 7

what is the glednoid cavity?

Answer 7

the shallow socket where the head of the bone is in.
- the shoulder girdle has exceptional flexibility
- can be easily dislocated

Question 8

characteristics of greater and lesser tubercles

Answer 8

-two bony projections opposite the head
- sites of muscle attachment

Question 9

what two bones make up the forearm?

Answer 9

radius (thumb) (lateral)
Ulna (medial) (pinky side)

Question 10

structure of hand

Answer 10

8 carpals
5 metacarpals
14 phalanges

Question 11

bony pelvis structure

Answer 11

pelvic girdle
sacrum
coccyx
coxal bones
ossa coxane

Question 12

what does the illium in the coxal hip bone connect to?

Answer 12

posteriorly with the sacrum at the sacroiliac joint
- large flat bone that makes up most of the hip

Question 13

false pelvis

Answer 13

-superior to the true pelvis
- area medial to the flaring portions of the illia

Question 14

female pelvic girdle vs male

Answer 14

female
- sacrum is shorter and less curved
- ischial spines are shorter and farther apart, thus the invite is larger
- pubic arch is more rounded because the angle of the pubic arch is greater

Question 15

what is the only bone in the thigh and is the strongest bone of the human body?

Answer 15

femur

Question 16

characteristics of femur

Answer 16

ball like head articulating with the socket of the hip bone

Question 17

what comes after the head of femur?

Answer 17

the neck (common fracture location for the elderly)

Question 18

What’s the purpose of the femur medially slanting running downward to join with the leg bones?

Answer 18

beings the knees in line with the body’s center of gravity

Question 19

distally on the femur are the…

Answer 19

lateral and medial condyles

Question 20

the lateral and medial condyles articulate with the…

Answer 20

tibia of the lower leg

Question 21

anteriorly on the distal femur is the ( ) which forms the joint with the ( ).

Answer 21

patellar surface
patella

Question 22

two leg bones

Answer 22

tibia (shin bone, larger, more medial)
fibula

Question 23

what holds the tibia and fibular together?

Answer 23

interosseous membrane

Question 24

what are at the proximal ends of the leg bones?

Answer 24

medial and lateral condyles

Question 25

what ti medial and lateral condyles do?

Answer 25

articulate with the distal end of the femur to form the knee joint

Question 26

what is it when there forms the inner budge of the ankle?

Answer 26

medial malleolus

Question 27

fibula characteristics

Answer 27

lies alongside the tibia and forms joints with both proximally and distally -thin and sticklike -has no part in forming the knee joint

Question 28

what is the lateral malleolus?

Answer 28

distal end of fibula forms the outer part of the ankle

Question 29

Tarsus (tarsals of the foot)

Answer 29

- forms the posterior half of the foot - composed of seven tarsals

Question 30

foot structure

Answer 30

5 metatarsals 14 phalangies 30 in each leg

Question 31

is the foot considers a part of the leg?

Answer 31

yes -weak arches = flat fleet or taller arches
