Q

What is the one joint that joins the appendicular skeleton to the axial skeleton? Why are they only joined at one point?

Q

What is the difference between the functions of the upper limbs compared to the lower limbs?

A

Upper limbs are built for flexibility whereas lower limbs are built for stability as they have to support the weight of the body

Q

Rhomboid minor and major

A

Minor is at the top and major is at the bottom, fibres run similar to middle of trapezius so they help with retraction

Comes from underneath the scapula and attaches its medial edge to the ribs
Important for protraction and upwards rotation

Q

Subclavius and pectoralis minor

A

Round the front of the shoulder, pulls scapula downwards so is involved in protraction and depression

21
Q

What nerve supplies levator scapulae?

A

Dorsal scapular nerve

22
Q

What nerve supplies the subclavius and pectoralis minor?

A

Medial pectoral nerve

23
Q

What are the superior rotators?

A

Serratus anterior and superior part of trapezius

24
Q

What are the inferior rotators?

A

Rhomboid major, rhomboid minor and levator scapulae

25
Q

Why does the glenohumeral joint have a lot of mobility?

A

Glenoid fossa is much smaller than the head of the humerus which allows it a large amount of space to move around

26
Q

Synovial joint

A

Has a capsule, ligaments, synovial membrane with synovial fluid in the joint cavity and cartilage

27
Q

What type of joint is the glenohumeral joint?

A

Synovial ball and socket joint

28
Q

Abduction

A

Arm taken away from the trunk and lifted up

29
Q

Adduction

A

Arm brought back down next to the trunk

30
Q

Flexion and extension

A

Bringing arm up in front of you
Bringing arm back down

31
Q

Hyperextension

A

Going backwards behind you

32
Q

Medial rotation

A

Going towards the midline

33
Q

Lateral rotation

A

Going away from the midline

34
Q

Circumduction

A

Going round in a big circle both forwards and backwards

35
Q

Deltoids location

A

Fastens in like a horseshoe around the clavicle and spine of the scapula and the acromium
Comes down and inserts into the humerus

36
Q

Middle portion of deltoid

A

Abducts the arm

37
Q

Front and back portions of the deltoid

A

Make abduction by the middle portion smoother by guiding it
If the front acts on its own it flexes the arm
If the back acts on its own it extends the arm

38
Q

Latissimus dorsi

A

Comes upwards and inserts into the humerus
Important for adduction and extendion of the arms

39
Q

Teres major

A

Short fat muscle on the side and has same function as latissimus dorsi

40
Q

Pectoralis major

A

Attaches to clavicle and sternum
Adducts and medially rotates the arm

41
Q

What nerve supplies the pectoralis major?

A

Medial and laterla pectoral nerves

42
Q

What stabilises the glenohumeral joint? How?

A

Glenoid labrum and the tendon of biceps brachii
Goes up and over the joint cavity and fastens to the top of the glenoid fossa to stop it moving upwards

43
Q

What are the rotator cuff muscles?

A

Supraspinatus, infraspinatus, teres minor and subscapularis

44
Q

What is the function of the rotator cuff muscles?

A

Attaching the scapula to the humerus and providing dynamic stabilisation

45
Q

What is another function of the supraspinatus?

A

Assists in abducting the arm

46
Q

Which rotator cuff muscles attach to the greater tuberosity?

A

Supraspinatus, infraspinatus and teres minor

47
Q

What nerve supplies the supraspinatus and infraspinatus?

A

Suprascapular nerve

48
Q

What nerve supplies the teres minor?

A

Axillary nerve

49
Q

Where is subscapularis located?

A

Between the scapula and ribcage
Inserts onto the lesser tuberosity of humerus
