Anatomical Planes & Directional Terminology I
The Transverse Plane divide the body into _______ and ______ portions.
Superior and inferior
The universal accepted starting point used to describe or analyze the body.
What is the anatomical position?
The joint that connects the superior appendicular skeleton to the axial skeleton.
What is the sternoclavicular joint?
What are all of the upper limb bones?
shoulder: scapula and clavicle
arm: humerus
forearm: radius and ulna
wrist: 8 carpal bones
hand: 5 metacarpal bones
fingers:14 phalanges
A nerve that runs posterior to the medial epicondyle.
What is the ulnar nerve?
Divides the body into front and back sections.
What is the Coronal Plane?
Another word for anterior
What is ventral?
The bone that keeps the upper limb away from the trunk to increase movement.
What is the clavicle?
The _____ is located in the superior lateral portion of the scapula and articulates with the head of the humerus.
The glenoid cavity
On the anterior surface of the wrist, a ligament stretches across the wrist to form the tubercle of the trapezium to the hook of the hamate to form the _______.
Carpel Tunnel
The anatomical term which best describes a structure toward the head is:
Superior
The wrist is _____ to the elbow
The part of the scapula that prevents dislocation of the humerus superiorly.
Your friend runs out of gas and you have to help push his car. Discuss the sequence of bones and joints that convey the forces passing from your hand, through your upper limb and your pectoral girdle, and to your axial skeleton. (Bones + Joints)
As you push against the car, forces will pass from the metacarpal bones of your hand into the carpal bones at the base of your hand. Forces will then pass through the midcarpal and radiocarpal joints into the radius and ulna bones of the forearm. These will pass the force through the elbow joint into the humerus of the arm, and then through the glenohumeral joint into the scapula. The force will travel through the acromioclavicular joint into the clavicle, and then through the sternoclavicular joint into the sternum, which is part of the axial skeleton.
The muscle whose tendon is contained in the intertubercular sulcus?
What is the long head of Biceps Brachii?
The Sagittal Plane divide the body into _______ and ______ portions.
The areas on the front and back of the hand are _________ and _______ respectively.
Palmar, Dorsal
The articular surface on the humerus at which the radius articulates with.
What is the Capitulum?
When a child is suddenly lifted/pulled up when forearm is in pronated position, head or radius may slips out partially from annular ligament. (Nursemaid's elbow)
Radial Head Subluxation
These are the three muscles that attach to the coronoid process of the scapula.
What are the Biceps Brachii, Coracobrachialis and Pectoralis minor?
When interpreting at CT scan, it is important to determine the orientation. Images are most commonly presented in the _________ plane, and are orientated so that we are looking _____ the body from the patient’s feet.
transverse, up
Which bony landmark is located on the lateral side of the proximal humerus?
Greater Tubercle
A bone that has a c shaped trochlear notch.
What is the ulna?
As the forearm rotates, the proximal end of the ____ stays in place and the ____rotates
Ulna, radius
Runs alongside the radial nerve in the radial groove posteriorly.
What is the Profunda Brachii artery?
