Upper limb 2 Flashcards
what compartment of the arm flexes the elbow and the shoulder joint
the anterior compartment of the arm
name the 3 muscles that make up the anterior compartment of the arm
biceps brachii, coracobrachialis and the brachial
where does the biceps brachii arise from
there are two heads - the short head arises from the coracoid process of the scapula and the long head arises from the supraglenoid tubercle
where does the biceps brachii tendon insert
onto the tuberosity of the radius
what are the actions of the bicep brachii muscle
flexion of the elbow joint, flexion of the shoulder joint and supinates the forearm
where does the short head of the biceps brachii arise from
the coracoid process of the scapula
where does the long head of the biceps brachii arise from
the supra-glenoid tubercle
what other muscle arises from the same location as the short head of the biceps brachii
the coracobrachialis
what are the attachments of the coradobrachialis muscle
the coracoid process of the scapula and the medial shaft of the humerus
what are the actions of the cracobrachialis muscles
flexion of the shoulder joint and adduction of the arm
what are the attachments of the brachialis muscle
from the distal half of the humerus to the coronoid process of the ulnar bone
what are the actions of the brachialis muscle
flexion of the elbow joint
what nerve innervates all of the biceps muscles
the musculocutaneous nerve
what muscle does the musculocutaneous pierce through on the way to the arm
the coracobrachialis
besides motor innervation to the biceps, what is the other role of the musculocutaneous nerve
sensory innervation to the lateral aspect of the forearm
what are the branches of the brachial artery
the radial and the ulnar artery
name the deep branch that is given off of the radial artery
the profound brachii
what is the role of the median nerve
innervates most of the forearm muscles
what cords form the median nerve
the lateral and the medial cords
what is the role of the ulnar nerve
innervation of some muscles in the forearm and sensory to some aspects of the hand
damage to what will result in damage tot he ulnar nerve
the medial epicondyle
damage to the surgical neck of the humerus will damage what nerve
the axillary nerve
damage to what will result in damage of the radial nerve
the radial groove of the humerus
what forms the base of the cubital fossa
an imaginary line between the 2 epicondyles of the humerus
what muscle forms the medial border of the cubital fossa
pronator teres
what muscle forms the lateral border of the cubital fossa
the brachiradialirs
what nerve innervates the tricep muscles
the radial nerve
what cord does the radial nerve come from
the posterior cord
what ligaments are found in the elbow
the ulnar collateral, the radial collateral and the annular
name the 3 flexors of the elbow
the biceps brachii, the brachioradialis and the brachialis
names the elbow extensor muscles
the triceps and the anconeus
name the 2 supinators of the arm
the biceps brachii and the supinator muscle
name the pronator muscles
the pronator teres and the pronator quadratus
