CPT Study Guide Flashcards
define inferior
away from the head; lower
define proximal
toward the center of the body or nearest the center form a point of reference
define distal
away from the center of the body or point of reference
define medial
toward the midline of the body
define lateral
away from the midline of the body; to the side
define contralateral
body part located on the opposite side of the body (right hand/left foot)
define ipsilateral
body part located on the dame side of the body (right hand/right foot)
define the sagittal plane
divides the body into the right & left sides. Flexion & extension exercises are primarily involved in this plane, also dorsiflexion & plantar flexion.
squats, bicep curls, walking & running are sagittal plane mvmts
define frontal plane
divides body into anterior & posterior (front/back) portions. vertical & lateral mvmts occur in this plane: abduction & adduction, lateral flexion at spine & inversion of the foot.
jumping, side lunges, lateral raises & windmills are frontal plane movements
define transverse plane
dividies body into superior & inferior (top/bottom) portions. horizontal & rotational mvmts take place in this plane: internal & external rotation, pronation & supination, horizontal abduction & adduction.
Trunk rotation & swinging a bat or horizontal abduction & adduction are movements in this plane
define longitudinal axis
straight line that cuts thru body form top to bottom. rotation around longitudinal axis takes place in transverse plane.
spinal rotation with twisting trunk is example of movement around longitudinal axis
How is the plane defined?
the plane in which the exercise occurs is in relation to the body NOT the position of the body.
jumping jacks & snow angels are both frontal plane movements
define flexion.
movement involving a decrease in joint angle (bending mvmt towards, closer)
bicep curl involves elbow flexion.
in a squat, the ankle, knee & hip joints are in flexion
define extension.
movement involving an increase in joint angle (straightening movement, extended, further, away)
lowering of bicep curl is extension of elbow joint
define adduction
movement toward the midline of the body
define abduction
movement away from the midline of the body
define plantar flexion
mvmt at ankle joint that points the foot downward (like a ballerina)
define dorsiflexion
movement at the ankle joint that points the foot up towards the leg (flexed feet)
define inversion
movement of foot which causes the sole of the foot to face inwards (rolling ankle severe example)
define eversion
movement of the foot which causes sole of foot to face outwards
define supination of foot
combo of plantar flexion (pointed foot), inversion (rolling ankle) and adduction (mvmt towards midline)
define pronation of foot
combo of dorsiflexion(flexed feet), eversion (sole faces outwards, rolls inward), abduction (movement away from midline of body)
define open chain movements
when a distal segment (hand/foot) moves in space
bicep curl, tricep extension, leg extension, leg curl)
define closed chain movement
occur when distal segment (hand/foot) are fixed in place
push up, pull up, squat, deadlift, lunge
What are the 5 major types of bones?
- long bones
- short bones
- flat bones
- irregular bones
- sesamoid bones
What are the 3 sections of the vertebrae column?
- cervical (head & neck, 7 vertebrae)
- thoracic (mid-back & 12 vertebrae)
- lumbar (low back, 5 vertebrae)
What are the 3 types of joints?
- fibrous
- cartilaginous
- synovial
What do tendons connect?
muscles to bones
what do ligaments connect?
bone to bone
What is the difference between Type 1 & Type 2 muscle fibers?
1 are slow-twitch muscle fibers, smaller, produce less force, slow to fatigue, higher aerobic capacity, muscles that act primarily as stabilizers generally contain greater concentrations of type 1
vs.
2 are fast-twitch, larger, white, produce more force, quick to fatigue, higher anaerobic capacity, muscles primarily responsible for joint movment contain greater concentration of Type 2.
what is meant by muscle extensibility?
ability to be stretched or lengthened
what is meant by muscle elasticity?
ability to return to normal or resting length after being stretched
what is meant by muscle irritability?
ability to respond to a stimulus
Define isometric muscle action
Occurs when contractile force of muscle is equal to resistive force, joints do not move.
Plank, wall sit
Define concentric muscle action
shortening portion of muscle where joint movement occurs
occurs when contractile force of muscle is greater than resistive force, moves in opposite direction of force or resistance.
Bicep contracts to flex elbow joint
Define eccentric muscle action
occurs when a muscle develops tension while LENGTHENING, occurs when contractile force of muscle is less than resistive force, moves in the same direction as the resistance.
Lowering portion of pull up or squat
define isotonic
same tone throughout a movement
define isokinetic
same speed throughout a movement
