anatomy review digits, hands and wrists

QuestionAnswer
how many bones are in the hand 27
the hand has how many divisions and what are they 14 phalanges, 5 metacarpals and 8 carpals
the thumb has how many phalanges only two phalanges
a single phalange is called what phalanx
are carpal bones considered part of the hand T or F true
digits or phalanges have four parts base, body, head, and terminal tuft
terminal tuft the distal head of the phalanx
another name for the thumb pollex
the digits are numbered 1-5 and named by location
first digit the thumb only has proximal and distal
another name for big toe hallux
digits 2-5 has proximal, middle and distal ends
metacrarpals are classified as 1-5 miniature long bones formed by endochondral ossification
metacarpals make up the palm of the hand
carpals are classified as 8 short bones
bones of the carpals have a layer of compact over spongy bone
what are the bones of the metacarpals lateral to medial 1. scaphoid or navicular 2. lunate - half moon 3. triquetrum 4. pissiform - pea shaped 5. trapezium - thumb, lateral or greater multangler 6. trapezoid or lesser multangler 7. capitate or os magnum 8. hamate - little hook process called
another name for hamate unciform
what carpal bone articulates with the base of the 3rd metacarpal? capitate or os magnum bone
which carpal bone is the largest os magnum bone
which carpal bone is the most commonly fractured scaphoid or navicular bone
the hand consists of how many bones 27
what carpal bone articulates with the base of the 1st metacarpal trapezium or greater multanger
the bones in the palm of the hand are referred to as metacarpals
interphalangeal joints proximal PIP and distal DIP
DIP distal interphalangeal joints 2nd-5th synovial hinges and diathrodial
PIP proximal interphalangeal joints 1-5 synovial and diathrodial
the thumb articulation has which joints IP and PIP
MCP articulations metacarpophalangeal joints 2-5 are ellipsoid and synovial
head of the metacarpals make up what? the knuckles
intermetacarpals joint articulations gliding and synovial
CMC joints carpometacarpals which are carpal/metacarpal joints which are gliding
intercarpal joints
radiocarpal joint radius and carpal
carpal tunnel flexor retinaculum. laterally attached to: trapezium and navicular medially attached to: hamate and pissiform
anatomical snuff box radio fossa floor made up of navicular and trapezium
sesamoid bone developed in tendons
common fractures scaphoid or navicular bone
common hand fractures bennetts and boxers
bennetts fracture found at base of first metacarpal
boxers found at the base of the 5th metacarpal is caused by punching a wall etc.
common wrist fractures colles', smiths and torus/buckle
colles posterior dislocation and fracture of carpal and radius/ulna
smith's anterior dislocation (mr. smith)
best position to see wrist fractures lateral
torus or buckle periosteum buckles, impacted fracture
the forearm consists of what two long bones the ulna and radius
medial side ulna
lateral side radius
ulnar anatomy proximal extremity - olecranon process is proximal and posterior coronoid process - is proximal and anterior trochlear notch and radial notch body distal extremity - head and styloid process
radial anatomy proximal extremity - consists of three parts head,neck and tuberosity body distal extremity - styloid process carpal articular surface/radial carpal joint and ulnar notch
distal extremity styloid process, carpal articular surface (radial carpal joint) and ulnar notch
anatomy of the humerus/ classification long bone.medial condyle is the trochlea which sits in the trochlear notch
proximal end of the humerus head of the humerus
distal end of the humerus articulates with the radius and ulna (elbow)
trochlea spool like process that sits in the troclea notch which articulates with the ulna
distal anatomy of the humerus/ anterior condyle, capitulum, trochlea, coronoid fossa, and radial fossa
capitulum also means little head. articulates with w/ radial head
radial fossa the radial process sits into
distal anatomy of the humerus/ posterior olecranon fossa, medial & lateral epicondyle, and ulnar groove
olecranon fossa olecranon process sits into
ulnar groove ulna nerve sits into on medial epicondyle
proximal anatomy of the humerus humeral head, anatomical neck, greater tubercle (lateral), lesser tubercle (medial), itertubercular groove, and surgical neck body deltoid tubercle
intertubercular groove called the bicepital groove, bicep muscle
surgical neck common area that breaks
deltoid tubercle raised area, deltoid muscle
coronoid process beak like process
monteggis fx of the proximal radius/ulna, elbow
anatomy of the elbow. what three bones make up the elbow? the humerus, radius, and ulna
what three joints are enclosed in a common capsule? the proximal radioulnar joint, humeroulnar joint, and the humeroradial joint
proximal ulnar joint synovial pivot joint which allows us to pronate our hand
humeroulnar joint synovial hinge joint- troclea and troclea notch
humeroradial joint head of the radius and capitulum
what are the three fat pads? posterior, anterior, and supinator
fat pads can become elevated when elbows are injured T or F? True
