HUMAN MOVEMENT SYSTEM
COMBINATION AND INTERRELATION OF THE NERVOUS, MUSCULAR, AND SKELETAL SYSTEMS
NERVOUS SYSTEM
COGGLOMERATION OF BILLIONS OF CELLS SPECIFICALLY DESIGNED TO PROVIDE COMMUNICATION NETWORK WITHIN THE HUMAN BODY
SENSORY FUNCTION
ABILITY OF THE NERVOUS SYSTEM TO SENSE CHANGES IN EITHER THE INTERNAL OR EXTERNAL ENVIRONMENT
INTEGRATIVE FUNCTION
ABILITY OF THE NERVOUS SYSTEM TO ANALYZE AND INTERPRET SENSORY INFORMATION TO ALLOW FOR PROPER DECISION MAKING WHICH PRODUCES THE APPROPRIATE RESPONSE.
MOTOR FUNCTION
NEUROMUSCULAR RESPONSE TO THE SENSORY INFORMATION
PROPRIOCEPTION
CUMULATIVE SENSORY INPUT TO THE CENTRAL NERVOUS SYSTEM FROM ALL MMECHANOREPTORS THAT SENSE BOYD POSITION AND LIMB MOVEMENT.
NEURON
THE FUNCTIONAL UNIT OF THE NERVOUS SYSTEM
SENSORY (AFFERENT) NEURONS
TRANSMIT NERVE IMPULSES FROM EFFECTOR SITES SUCH AS MUSCLES AND ORGANS VIA RECEPTORS TOT HE BRAIN AND SPINAL CORD
INTERNEURONS
TRASMIT NERVE IMPULSES FROM ONE NEWRON TO ANOTHER
MOTOR (EFFERENT) NEURONS
TRANSMIT NERVE IMPUSES FROM THE BRAIN AND SPINL CORD TO EFFECTOR SITES
CENTRAL NERVOUS SYSTEM
PORTION OF THE NERVOUS SYSTEM THAT CONSISTS OF THE BRAIN AND SPINAL CORD
PERIPHERAL NERVOUS SYSTEM
CRANIAL AND SPINAL NERVES THAT SPREAD THROUGHOUT THE BODY
Mechanoreptors
Sensory receptors responsible for sending distortion in body issues
muscle spindles
receptors sensitive to change in length of the muscle and the rate of that change
golgi tendons
receptors sensitive to change in tension of the muscle the rate of that change
joint recptors
recptors surroundig a joint that responds to pressure acceleratin and deceleration of the joint
sketal systems
the bodys framework composed of bones and joints
bones
provide a resting fround for muscles
joints
junctions of bones, muscles, and connective tissue at which movement occurs.
Axial skelton
Portion of the skeletal system that consists of the skull, rib cage
appendicular skeleton
portion of the skeletal systems that includes the upper and lower extremeities
remodleing
the process of resorption and formation of bone
osteclasts
a type of bone cell that removes bone tissue
osteoblasts
a type of cell that is responsible for bone formation
epiphysis
the end of long bones, which is mainly composed of cancellous bone
diaphysisi
the shaft portion of long bone
epiphyseal
the region of long bone connecting the diphysis t the epipysis
periosteim
a dense membrae composed of fibrous connectiv tissue that closely wraps all bone, except that of the articulating surfaces in joints, which are covered
medullar cavity
the central cavity of bone shafts where marrow is stored
articular cartilage
cartilage that covers the articular suraces of bones
depressions
flattened or indentied portions of bone
processes
projections protruding fro the boe where muscles, tendons, and ligaments can attach
v ertebral column
a series ofirregularly shaped bones called vertebrae
arthrokinematics
joint motion
synovial joints
joints that are hel together by a joint capsule and ligaments and are most associated with movement in the body .
nonsynovial joints
joints that do not have a joint cavity
ligament
Primary connective tissue that connects bones together and provides stability, input to the nervous system, guidance and the liitation of mproper joint movement
muscular system
Series of muscles that moves the skeleton
Epimysuim
A layer of connective tissue that is underneath the fascia and surrounds the muscle.
Perimysium
the connective tissue that surrounds fascicles
endomysium
The deepest layer of connective tissue that surrounds individual muscle fibers
tendons
connective tissues that attache muscle to bone and provide an anchor for muscles to produce foorce
Sacromere
The functional unit of muscle that produes muscular contrction and consists of repeating sections of actin and myosins
Neural activation
The contraction of a muscle generated by neural stimulation
Motor unit
a motor neuron and al of the muscle fibers it innervates
neurotransmitters
chemical messengers that cross the neromusclar junction
