Bones of the Arm, Pectoral Girdle, Vertebrae, & Ribs

QuestionAnswer
This provides a point of attachment for the deltoid and trapezius muscles. Acromion Process
Shoulder muscles of the pectoralis minor, coracobrachialis and short head of the biceps attach here. Coracoid Process
This portion of the humerus articulates with the Glenoid Cavity of the scapula. Head of Humerus
This articulates with the manubrium fo the sternum at its clavicular notch. Sternal End of Clavicle.
This allows for attachment of the ribs to the sternum. Costal Cartilage
The number of true ribs 7
Attachment of the true ribs occurs where. T1 through the T7 vertebrae and costal cartilage of the sternum.
The number of false ribs. 3
Why are the false ribs called so. They don't attach directly to the sternum by way of costal cartilage but rather they attach to the costal cartilage of the 7th true rib.
This portion of the clavicle articulates with the acromion process of the scapula Acromion End.
A common shoulder problem occurs between these two processes of the scapula Acromion and Coracoid Process commonly called AC Joint problems.
This divides the scapula into areas of the supraspinatus fossa and the infraspinatus fossa. Spine
The point of origin for the supraspinatus and infraspinatus muscles is Infraspinatus and Supraspinatus fossas
This portion of the Humerus serves as the insertion for the supraspinatus, infraspinatus, teres minor and the lateral head of the triceps Greater Tuberosity or Greater Tubercle
This recieve the olecranon of the ulna when the arm is extended. Olecranon Fossa
This portion of the humerus gives attachment of teh ulner collateral ligament, Pronator Teres and flexor muscles of forearm. Medial Epicondyle
A depression for the coronoid process of the ulna Coronoid Fossa
This serves as an attachment for the subscapularis Lesser Tubercle
A large bump on the humerus that provides an attachment for the deltoid muscle. Deltoid Tuberosity
This portion of the humerus is occupied by the long head of the biceps tendon. Intertubercular or Bicipital Grove.
This superior portion of the ulna articulates with the trochlea of the humerus Trochlear Notch
This Process of the ulna is recieved by the fossa of the humerus. Coronoid
This portion of the of the radius articulates with a notch of the ulna allowing rotational movement causing supination and pronation Head of Radius
Insertion of the biceps brachii tendon occurs here. Posterior ( Rough Portion) of Radial Tuberosity
A bursa between the bone and the biceps tendon is located here. Anterior ( Smooth Portion) of Radial Tuberosity
The tendon of the brachioradialius attaches to the base of this process of the radius Styloid Process
The Redial Collateral ligament of the wrist attaches to this portion of the radius Apex or point of the Styloid Process
A common fracture of the wrist where the scaphoid bone is forced against the styloid process is called? Chauffeurs Fracture
The bony prominance felt as the elbow and functions to protect the end of the humerus Olecranon Process
This allows the radius to articulate with the ulna in positioning the hand in supination and pronation. Radial Notch of Ulna
This portion of the Ulna allows for the attachment of the brachialis. Ulna Tuberosity
This portion of the ulna, allows attachment fo the ulnar collateral ligament fo the wrist. Styloid Process of Ulna
Pronation of the hand shows the palm in what direction. Palm Down
Supination of the hand show the palm in what direction. Palm Up
Which group of phalanges has no medial or intermediat phalange. That of the Thumb
This carpal articulates with the styloid process of the ulna. Pisiform
This carpal articulates with eht head of the ulna. Triquetrum
This is the only carpal to articulate with 2 metacarpals making up the last two phalanges Hamate
This carpal articulates with the medial head of the radius. Lunate
This is one of the most frequently dislocated carpals of the hand Lunate
This carpal articulates with the middle metacarpal Capitate
This carpal articulates with the lateral head of hte radius and plays an important row in wrist movement. Scaphoid
This carpal articulates with the index finger at the index metacarpal. Trapezoid
This carpal articulates with the metacarpal of the thumb. Trapezium
