Answer 2

antebrachium

Question 3

upper limb consist of what bones

Answer 3

humerus, ulna, radius, carpal bones, metacarpal bones, and phalanges

Question 4

what is the single bone of the upper arm or brachium

Answer 4

the humerus

Question 5

what are the 2 bones of the antebrachium

Answer 5

ulna and radius

Question 6

explain the positions of the ulna and radius in anatomical position

Answer 6

radius is lateral side and ulna medial side

Question 7

explain the appedicular skeleton

Answer 7

includes all of the limb bones, plus the bones that unite each limb with the axial skeleton

Question 8

the scapula and clavicle makes up the

Answer 8

pectoral girdle

Question 9

what is the pectoral girdle

Answer 9

the bones that each upper limb to the axial skeleton form the girdle

Question 10

what is the end of the clavicle that is thicker

Answer 10

the sternal end

Question 11

what is the sternal end

Answer 11

forms a very stable joint with the manubrium of the sternum (sternoclavicular joint)

Question 12

what is the flat end of a clavicle

Answer 12

acromial end

Question 13

what is the acromial end

Answer 13

forms a joint with the acromion of the scapula (acromioclavicular joint).

Question 14

which end of the clavicle is less stable

Answer 14

the acromial end

Question 15

clavicle landmarks

Answer 15

sternal end, acromial end, shaft, conoid tubercle, subclavian groove

Question 16

what attaches and what does the conoid tubercle do

Answer 16

the conoid ligament attaches here. It is one of the 2 ligaments that make up the coracoclavicular ligaments. It helps stabilize the scapula to the clavicle

Question 17

explain the subclavian groove

Answer 17

an indent that runs along the underside (inferior aspect) of the clavicle, this is where the muscle subclavius attaches

Question 18

scapula landmarks

Answer 18

medial (vertebral) border, lateral (axillary) border, superior border, superior angle, inferior angle, spine of the scapula

Question 19

fossa of the scapula

Answer 19

supraspinous fossa, infraspinous fossa, subscapular fossa, glenoid fossa/cavity, suprascapular notch

Question 20

processes of the scapula

Answer 20

coracoid process, acromion process

Question 21

tubercles of the scapula

Answer 21

supraglenoid tubercle, infraglenoid tubercle

Question 22

muscle that orginates in the fossas of the scapula

Answer 22

supraspinous fossa - supraspinatus
infraspinous fossa - infraspinatus
subscapular fossa - subscapularis

Question 23

what attaches at the coracoid process

Answer 23

“PBC” pectoralis minor
short head of the BICEPS brachii
coracobrachialis

Question 24

what attaches at the acromion process

Answer 24

attachment sites for the deltoid and trapezius muscles

Question 25

explain the glenoid fossa/cavity

Answer 25

depression that forms scapular portion of the glenohumeral joint or shoulder joint
this joint is least stable joint in the body and dislocations are common

Question 26

what attaches at supraglenoid tubercle and infraglenoid tubercle

Answer 26

long head of biceps brachii attach at supra and long head ofm triceps brachii atttach

Question 27

what runs through the suprascapular notch

Answer 27

the suprascapular nerve

Question 28

a projection or outgrowth of bone

Answer 28

process

Question 29

a depression in the bone

Answer 29

fossa

Question 30

small, roundish outgrowths of bone

Answer 30

tubercle

Question 31

larger than tubercles, less round and more varied in shape

Answer 31

tuberosity

Question 32

indentation or divot in the bone

Answer 32

notch
