Lesson 1 Flashcards
Articulate
Where two surfaces come into contact with each other
Palpate
Examined by touch
Flexion
Bending - reduces the angle at a joint
Extension
Straightening - increase the angle at a joint
Abduction
Movement away from the midline
Adduction
Movement toward the midline
Opposition
Moving the pinky and thumb toward each other
Reposition
Returning to neutral position
Supinate
Rotation of the forearm away from the midline (palms up)
Pronate
Rotation of the forearm toward the midline (palms down)
Circumduction
Moving through all of its axis – not a pure movement
Superficial
Nearer to the surface
Deep
Farther from the surface
Medial
Nearer to the median plane (midline of the body)
Proximal
Nearer to trunk or point of origin
Distal
Farther from trunk or point of origin
Lateral
Farther from median plane
Posterior
Nearer to the back
Anterior
Nearer to the front
Inferior
Situated below
Superior
Situated above
Prone
Lying face down
Supine
Laying face up
Elevation
Raising a structure
Depression
Lowering a structure
Rotation
Movement around an axis
Hyper extension
Movement beyond its normal range
Ulnar deviation
Moving the hand medially
Radial deviation
Moving the hand laterally
Plantar surface
Sole of the foot
Dorsal surface
Top of the foot
Inversion
Sole toward the midline (turns inward)
Eversion
Sole away from the midline (turns outward)
Palmar surface
Palm of hand
Dorsal surface
Back of the hand, pertaining to the back or posterior
The skeletal system provides … for the body
Framework
How many bones do we have?
206
What do bones function as for our body?
Protection, support, locomotion or movement
What are bones composed of?
Cells
blood
minerals (calcium carbonate, calcium phosphate)
What are joints?
Connections between the bones which work with muscles to provide movement
What are the different types of joints?
Ball and socket joints
Hinge joints
Ball and socket joints
Allow a wide range of movements in many directions
Found at hips and shoulders
Hinge joints
Found at the knees and elbows and allow movement mainly in one direction
What are the three main bones in the arm?
Humerus
Ulna
Radias
Humerus
Largest bone of arm
Found in Upper arm
Ulna
Is the larger of the two bones of the lower arm (forearm)
On the same side as your baby finger
Articulates with the humerus to form the elbow joint
Radius
Smaller of the two bones in the lower arm
On the same side as your thumb
It is called the radius because it can rotate around the ulna
The ulna and radius intersect at the hand forming the wrist joint
Where does the humerus join to the body?
At the shoulder

Radius and ulna articulate with each other to provide
Pronation & Supination
They also articulate with the carpal bones to form the wrist
Carpals
This is the wrist and it is composed of eight (8) small regular bones
They allow flexion and extension of the wrist and ulnar and radial deviation
Metacarpals
These are five (5) bones which make up the bones of the palm of the hand
When you clench your fist, the heads of the metacarpals become prominent and are called your knuckles
Phalanges
These are the bones of the fingers or digits
There are 14 bones consisting of 3 phalanges on each finger and 2 in the thumb 
The outer most bones are called distal, the middle is called medial, and the ones nearest the hand are called proximal
The thumb has only distal and proximal phalanges
