Class 2 Flashcards
Where does the ulna connect with
Trochlea of humerus
Where doe radius connect
Capitulum
Where does olecranon of ulna connect
Olecranon fossa
What is above the trochlea
Coronoid fossa
What is above the capitulum
Radial fossa
How do you differentiate between epicondyles
Medial is larger and extends more
What runs between tuberosity
Intertubercular groove
What are the muscles of anterior arm
Biceps brachii
Coracobrachialis
Brachialis
What are the actions of biceps
Flexoin
Supination
What are the actions of other anterior arm muscles
Flexion
Wha nerve innervates anterior arm muscles
Musculcutaneous
Where does biceps attach
Long head - supraglenoid tubercle
Short head - coracoid process
Into radial tuberosity of radius
Where does carcobrachialis attach
Coracoid process - medial humerus
Found underneath detoid / biceps
Where does brachialis attach
Coronoid process of ulna + ulnar tuberosity
What artery supplies the arm
Brachial
How are the arteries in the arm broken up
Subclavian - axillary at 1st rib
Brachial at teres major
Radial and ulnar at cubital fossa
Course of median and ulnar nerve
Ulnar nerve - most medial Ulnar artery Median nerve - very deep Radial artery Radial nerve - deep behind muscle
What is the lymphatic drainage of the arm
Axillary lymph node
Where does lymph from RUQ go
Right lymphatic duct
Where does lymph from everywhere else go
Thoracic duct
What would fracture of radial groove damage
Radial nerve
What would fracture of medial epicondyle damage
Ulnar nerve
What would surgical neck fracture damage
Axillary nerve
What are the medial and lateral borders of cubital fossa
Medial = pronator teres Lateral = brachioradialis
What is the contents of the cubital fossa
Brachial artery branching
Radial nerve is deep
Ulnar nerve medial to radial artery
What occupies the posterior arm
Triceps
Anaconeus
What is the function of the posterior arm
Extension of elbow
What is the arterial and nerve supply
Profunda brachii
Radial nerve
Where does triceps insert
Olecranon process
What is clinical of radial nerve injury
Wrist drop
What type of joint is the elbow joint
Synovial hinge
What movements occur at the elbow joint
Flexion
Extension
What are the connections of the elbow joint
Trochlear notch of ulna + trochlea
Head of radius + capitulum
Olecranon into olecranon fossa
What ligaments support the elbow joint
Medial collateral
Lateral collateral -
Annular
What does annular do
Holds head of radius
What does lateral collateral connect with
Lateral epicondyle - annular
What does medial collateral connect with
Medial epicondyle -> coronoid process of ulna + olecranon
What type of joint is radio-ulnar joint
Synovial pivot
Fibrous syndesmosis in the middle
What are the proximal and distal attachments
Proximal
Radial notch of ulna and radial head
Distal
Ulnar notch of radius and ulnar head
What allows supination
Biceps brachii
Supinator - very deep attached to bone
What allows pornation
Pronator quadratas
Pronator teres
Where is the coronoid process of the ulna
Anterior
Opposite olecranon
