Q

Coricobrachialis attachments?

A

Coricobrachialis Proximal attachment: coricoid process Distal attachment: medial shaft of humerus

24
Q

Brachialis attachments?

A

Proximal mid shaft,anterior surface of humerus Distal attachment: coronoid process of ulna

25
Q

Triceps Brachiii attachments?

A

Proximal attachment Long head to infraglenoid tubercle; lateral head to posterior surface of humerus. above spiral groove, medial head to posterior surface of humerus, below spiral groove. Distal attachment Olecranon process of the ulna

26
Q

Which vein do we draw blood from? and Why?

A

Median Cubital Vein is one of the most important veins clinically because that is where they usually draw blood from. The median cubital vein is also above the bicipital aponeurosis thus, it is even safer to draw blood from the median cubital vein without having to worry about puncturing the brachial artery since it bifurcates below the aponeurosis

27
Q

Cephalic Vein and Basilic Vein is what to the arm in accordance to location?

A

Cephalic Vein- Lateral Basilic Vein - Medial

28
Q

Flexion muscles are?

A

Brachialis, Biceps Brachii

29
Q

Extension muscles?

A

Triceps Brachii and Anconeus

30
Q

Supination muscles?

A

Supinator

31
Q

2 joint muscles?

A

Long Head of tricep Brachhii and Biceps Brachii.

32
Q

What muscles are these? and What comes from between them?
