Hand/Wrist: how many minature long bones are there in the phalanges?
14 miniature long bones
Hand/Wrist: how many minature long bones are in the metacarpals?
5 minature long bones
Hand/Wrist: how many short carpal bones are in the wrist?
8 short carpal bones
Hand/Wrist: for phalanges digits are numbered 1-5. Starting with the thumb as ____. Each finger has 3 phalanges ______,______, and ______.
- # 1
- proximal, middle, distal
Hand/Wrist: The thumb only has _____ phalanges the ______ and ______.
2, proximal and distal
Hand/Wrist: Each phalanx (individual phalange) has a ______(which is proximal), ________(shaft) and a ________(distal).
base, body, round head.
Joints of Hand/Wrist: the thumb only has 2 phalanges so it on has a _______ joint.
Interphalangeal (IP)
Hand/Wrist: where is the first metacarpophalangeal (MCP) joint located?
the joint between the proximal phalanx and the first metacarpal.
Hand/Wrist: when x-raying the thumb the ___________ must be included in all 3 views (include from tip of distal phalanx to _____)
entire first metacarpal, (base of first metacarpal)
Hand/Wrist: fingers have ___ phalanges so they contain the ________,_________, and ________ joints.
- 3
- distal interphalangeal joint (DIP)
- Proximal interphalangeal joint (PIP)
- metacarpal phalangeal joint (MCP)
Hand/Wrist: when x-raying the fingers, include from the _______ to __________.
tip of distal phalanx to proximal 1/3 metacarpal.
Hand/Wrist: What are the 8 carpal bones in order from the proximal row starting on thumb?
Scaphoid, Lunate, Triquetrum, Pisiform, Hamate, Capitate, Trapezoid, and Trapezium. So Long To Pinky Here Comes The Thumb).
Radius/Ulna: the radius is on the ______side and the ulna is on the ______ side.
- thumb side
- ulna is on the pinky side.
Radius/Ulna: the radius and ulna articulate with eachother at the ___________ (joint). Which allows?
proximal and distal radioulnar joint. This allows rotational movement of the forearm, wrist, and hand.
Radius/Ulna: where is the head of the Radius located?
The proximal end of the radius (near the elbow)
Radius/Ulna: Where is the neck of the radius located?
constricted area just below the head
Radius/Ulna: What is radial tuberosity and where is it located?
rough oval process on the radius, just distal to the radial neck.
Radius/Ulna: where is the head of the ulna?
distal end near the wrist.
Radius/Ulna: what is the proximal ulna?
longer of the 2 bones of the forearm primarily involved in the formation of the elbow joint.
Radius/ulna: describe the olecranon process of the ulna.
beak-like process palpable on posterior surface (funny bone)
Radius/Ulna: is the coronoid process of the ulna a beak-like process?
yes
Radius/Ulna: describe the trochlear notch of the the ulna.
Large, concave, depression that articulates with distal humerus.
Radius/Ulna: describe the radial notch of the ulna.
shallow depression on lateral side of ulna that the head of the radius fits into.
Humerus: what is the distal portion of the humerus composed of?
Body- larger center portion (shaft)
Humeral Condyle- expanded distal end of the humerus.
Trochlea- on ulnar/medial side (anatomic position), articulates with the ulna.
Capitulum- on radial/ lateral side (anatomic position), articulates with the head of the radius.
Epicondyles- above the condyles, medial which is above the trochlea and larger and lateral which is smaller and is above the capitulum.
Humerus: what are the 2 types of depression/fossae of the distal humerus? what are they composed of?
Anterior fossae: composed of a radial fossa (lateral side recieves radius when arm is flexed)
Posterior fossae: composed of the olecranon fossa (recieves olecranon when arm is flexed)
