Anatomical Kinesiology Quiz Flashcards

muscle tension
Terms Definitions
Autonomic
sub-conscious movement/reflexes
Superior (Cephalic)
Above
Three main planes
SagitalFrontalTransverse
Types of Bones
Long
Short
Flat
Irregular
Sesamoid
Horizontal ADDuction
ABduction (Protraction)
Contralateral
The opposite side
Stability
The resistance to displacement
Kinesthesis
Body awareness and control
attach muscle to bone
Tendon
Isotonic Contractions
Developes tension

Causes movement

Dynamic Contractions = movement
Prone
Body lying face down
osteoblasts
cells that form new bone
Why Study Kinesiology?
*3 Fold Purpose
Safety
Eeffectiveness
Efficiency
contains medulla, pons, cerebellum, and midbrain
Brainsteam
tibialis posterior (actions)
plantar flexion, inversion
1st Class Lever
Produce Balance Movements

SeeSaw

Force > Axis > Resistence

e.g. heah knod
ADduction
Movement medially, towards the midline

Frontal Plane
Quickness (lever arm)
Shorter Lever Arm
Appendicular Skeleton
Extremities, Shoulder Girdle, and Pelvis
3 Major Joint Classifications
Synarthrodial: No Movement
 
Amphiarthrodial: Slightly Moveable
 
Diarthrodial: Versatile
Muscles used for Flexion
Pec Major(C)
Deltoid(ANT)
Bicep Brachii
contain the proteins for contraction in muscle cells
Myofibrils
Plantarflexion
Extension of the ankle

Moving the foot away from the body
Synarthrodial Joint
Immovable joint

e.g. Sutures of skull, Gomphosis of teeth
Peripheral Nervous System
Nerves outside Central Nervous System
Levels of Organization in Anatomy (small to big)
ChemicalMoleculeCellTissueOrganOrgan SystemOrganism
occur when active muscle lengthensex. downward negative motion of a bicep curl
eccentric contractions
Pivot Joint (Trochoid)
Uniaxial Art

Transverse plan (in anatom. position)

Radial bone movement/ Atlanto-Axial movement
External Rotation
Rotary motion around longitudinal axis of a bone

Away from the midline
Circumduction
Circular movement of a limb (cone shaped ROM)

AKA Circumflexion
Exteroceptors
Neurons that react to our 5 senses and
the external enviroment
extends from top of head to feet splitting body in right and left sides (flexion, extension, hypertension moves)
Sagittal
divides body into top and bottom parts
Transverse Plane
flexor digitorium longus (actions)
plantar flexion, inversion, flexion of the 4 lesser toes
Plane of Motion
Imaginary two dimensional surface for which limbs/body moves
What is a nerve?
Bundle of Neurons enclosed in connective
tissue known as a sheath
most common type of bone is the long bone and has weight bearing, and short bones are in hands and feet
Bones
is a series of bony segments linked together at a pivot point called a joint
Human skeleton
Volar
Palm of the hand or sole of the foot
Golgi Tendon Organ (GTO)
In tendon close to muscle-tendon junction

Sensitive to:
- Muscle Tension
- Active Contraction

Less sensitive to stretch
Extensibility (muscle)
ability for muscle to be stretch back to its original length post contraction

e.g. spring like
What is the main function of skeletal muscle
Movement and Posture
-made up of sensory nerves that relay messages from senses throughout body and back to CNS-neurons are cells that receive and send messages throughout the nervous systemSensory neurons go to brain or spinal cord, Efferent neurons carry signal
Peripheral Nervous System
Base of Support
Balanced is achieved when COG is in it

Larger BOS = more balance

COG at Edge of BOS = poor balance
Golgi Tendon Organ Order of Operations
Tension in muscle increases and activates GTO

1. GTO threshold reached

2. Impusle to CNS

3. CNS causes inhibition (relax)

4. Activates Antagonist as a protective mechanism
