CNS
Brain and Spine
is made up of nerves that extend and travel to and from the brain and spinal cord
Peripheral Nervous system
The contain a cell body, dendrites, and an axon
Neurons
automatic / subconscious responses to a stimuli
Reflex
information that is arriving To the brain are known as what?
Affectors
_____ neurons carry messages to the central nervous system
Sensory
what are the names of the nerves that travel from the brain and the spine
Cranial and Spinal Nerves
chemical messengers that move across the synapse (Ex Dopamine, Adrenalin)
Neurotransmitters
what organ is not part of the neural pathway of a reflex
brain
composed of gray matter ultimate control and processing center.
cerebrum / Cerebral cortex
in charge of voluntary movements, interpretation , sensory interpretation, consciousness, and cognition.
the Brain
this division of the nervous system activates the body fight or flight response
Sympathetic Division
The part of the cell that Receives impulses from previous neurons.
Dendrites
known as a relay neuron its job is to Carries information from sensory neuron to motor neuron
Interneuron
the pons medulla and mid brain make up what structure
Brain Stem
largest part of brain stem handles unconscious processes and jobs, such as your sleep-wake cycle and breathing
Pons
Allows us to make voluntary, conscious decisions, such as standing up or raising your hand in class
Somatic Nervous system
These help messages travel faster and smooth through the cells and aid with insulation.
Myelin Sheath
the main function of a reflex is t help the body maintain _______?
homeostasis
in charge of Interpreting visual information received from the eyes. Recognizing and understanding what we see.
Occipital lobe
collects information touch, pain, pressure, vision, taste from internal and external stimuli of the body and carries them to the CNS.
Sensory Division
Control processes that happen subconsciously (we can’t control), such as the rate of our heart, the peristalsis of our intestines, or the release of sweat from sweat glands
Autonomic Nervous system
What is the SOMA
Cell Body
Receptor - Sensory Nuron - Integration center - Motor neuron - Effector is considered _______?
Neural Pathway
How many parts (hemispheres) does your cerebellum have?
