Allows for slight movements
Cartilaginous
Contains cartilages that is attached to bone
Diathroses
Permits full movement
Hinge Joint
Movement in one direction
Ball and socket
Rounded head fits into joint
Synovial fluid
Acts as lubricant, more mobility
Gliding
Joint surfaces are flat
Pivot
Joints move in pivot like motion
Myo
Word part for muscle
Sarcomere
Basic contractile unit of muscle cell
Myosin
Pulls acting fibers toward the middle shorten the length of the muscle
Fascia
Sheet of fibrous membrane that closes muscles and snakes groups
Ligaments
Connects bones or cartilage
Tendons
Bind muscle to bone
Flexor
Decreases the angle of a joint
Extensor
Increases angle of a joint
Abductor muscle
Moves bone away from midline
Adductor
Moves bone toward the midline
Sphincter Muscle

Alges-
Pain
Integration
Processors info and decides what should be done with it
Motor output
Brain decided to act and sends signals with instructions on what to do
Sensory neurons
Eyes and ears and other sense organs Z
Central Nervous System
Brain and Spinal Cord
Dura mater
Outer layer of CNS
Arachnoid
Middle web like later of CNS
Pia Mater
Innermost compact layer of CNS
Peripheral Nervous System
consists of the nerves and ganglia outside the brain and spinal cord.
Spinal Cord
Extension of the brain,
Somatic NS
Allows voluntary movement
Nervous tissue
Densely packed with differnt nerve cells
Neuron
Nerve Cell
Glial Cells
Provide nutrition support insulation. And he’ll with transmission
Dendrite
Numerous short nerve process that pick up neurotransmitter from other neurons
Axon
Long nerve cells that carry impulse from cell body Down to the axon terminals
Myelin Sheath
Insulating covering of axon and helps impulses
Node of Ranvier
Gap in sheath that helps facilitated rapid conduction of the nerve impulse down the axon
Axon terminal
Release neurotransmitter into the synaptic space to continue transmission
Neurotransmitter
Chemical substance that act at synapses to stimulate impulse
Synapse
Extremely small space in between neurons
Action potential
Change in electrical charge
Reflexes
Sensory neurons bring in stimuli, automatic reaction
