Elbow
This joint is made up of the trochlea of the humerus and the trochlear notch of the ulna and the head of the radius
Elbow Joint
What muscle inserts on the radial tuberosity and the primary movement is elbow flexion
Biceps Brachii
the glenoid fossa of the scapula and the head of the humerus make up this joint
Shoulder Jt.
the muscle that originates at the external occipital protuberance, superior nuchal line, and the spinous process of the cervical vertebrae and inserts on the later 1/3 of the clavicle and acromion process
Upper Trapezius
Transverse plane, Veritcal axis
The elbow joint is what type of axial joint?
Uniaxial
What muscle inserts on the olecronan process and the primary movement is elbow extension
Triceps Brachii
The sternum, clavicle, scapula, sternoclavicular joint, acromioclavicular joint and the scapulothoracic joint make up ____________
Shoulder girdle
The muscle(s) that originate on the spinous process of C7-T5 and insert on the vertebral border of the scapula is:
Rhomboid muscle (Major and Minor)
What are the three arthrokinematic movement of the shoulder joint
roll, glide , spin
The osteokinematic degrees of motion for the elbow are:
Flexion is 0-150 degrees
Ext is zero (with some hyperext.)
What muscle originates at the later superconylar ride of the humerus and inserts at the distal lateral aspect of the radius, proximal to the styloid process (AKA the drinking muscle)
Brachioradialis
scapulohumeral rhythm has a _____ ratio of humerus to scapular movement
2:1
The muscle that is involved in winging of the scapula is:
Serratus Anterior Muscle (O: Lateral surface of ribs 1-8 and I: Anterior surface of vertebral border)
The muscle that originates at the lateral 1/3 of the clavicle and inserts on the deltoid tuberosity is
Anterior Deltoid
Name all motions of the elbow joint
Flexion and extension
an angle formed by the arm and forearm when in the anatomical position is known as
Carrying Angle (Cubitus Valgus)
10-15 deg in females, 5 deg in males
when the scapula moves away from the vertebral column, this motion is called:
Protraction
This muscle inserts on the corocoid process and helps with protraction of the shoulder
Pectoralis Minor
The muscle that originates at the corocoid process and inserts on Medial surface of the humerus near the midpoint
Coracobrachialis Muscle
what are the 2 osteokinematic motions of the forearm
Supination and Pronation (typically 0-80 Degrees)
What is the Arthrokinematic motion of the Humeroulnar joint
Mostly glide!
Movement of the medial border of the scapula posteriorly is known as:
Scapular winging
Muscles originates at the Transverse process of C1-4
inserts Vertebral border of scapula between superior angle and spine of scapula
Levator Scapula
The only muscles of the Rotator Cuff group that causes internal rotation
Subscapularis
