Answer 1

please don't interrupt I'm way too stressed out to deal with people right now

This is my attempt to memorize/understand the structures presented in these figures from my anatomy textbook
Figures: 6.3 b,c,d,e
6.4
6.14 a
6.16 a
6.22 a,c
6.23 b,c
6.25 a
6.26 a
7.2 a
7.5 a,c
7.6 a,d
7.7 a,d
7.8 b
7.9 a
7.11 a
7.13 a,d
7.15 a
7.16 a,c

Answer 2

\({\bf{7.2a~Upper~Limb~and~Pectoral~Girdle:}}\)



(kind of ran out of room near the bottom but it's alright, we'll cover the hand later anyways)

Answer 3

start w/ the pectoral girdle, which connects the upper limb to the axial skeleton

the collarbone is the clavicle and the shoulder is the scapula

Answer 4

the arm (remember, anatomically speaking the arm is only the part from the shoulder to elbow) is composed of a large bone called the humerus, informally called the funny bone

Answer 5

now be careful w/ the orientation of the next two bones. this is the right arm (from the perspective of the subject) in the anatomical position so the thumb is facing away from the midline. the radius and ulna are labelled thusly (the radius is the bigger one)

Answer 6

then we have the bones of the wrist/hand

the wrist bones are the carpals (can remember "carpal tunnel' which affects the wrist)

then going down we have the metacarpals and phalanges (ph sounds like fingers, so the phalanges are the finger bones)

that's it, this one is very easy

Answer 7

\({\bf{7.5a~Scapula~(anterior):}}\) this one can be tricky especially since we are expected to know the anterior and posterior view but maybe this will help

Answer 8

we can start from the bottom and move our way up

since this is a right scapula (from the perspective of the subject) the border on the right side of the diagram is the medial border (also called ventral border) and the one on the left is the lateral border (axillary border)

Answer 9

then we have a flat surface called the subscapular fossa (remember, fossa = flat surface

the lateral angle is a projection on the lateral side

and adjacent to that is the rim of the glenoid cavity

Answer 10

finally we have a lot of structures (5) from the left to right

the acromion is a pointed projection where the scapula attaches to the shoulders (remember, acromial means having to do with the shoulders)

the coracoid process is the next major projection that sticks out

then there's a notch called the suprascapular notch

the border on the top part of the scapula is the superior border

and following that is an angle-shaped projection called the superior angle

Answer 11

for the posterior view (7.2c) we will be borrowing some structures, but be aware of the position changes

Answer 12

the acromion, body, medial border, laterial border, supraspinous fossa, coracoid process, etc. are still there, just in diff. locations

Answer 13

(this is still a right scapula so the medial is on the left)

then we add label spine for the long structure and a neck for a small rounded projection under the head
