The Nervous Systems
TRUE or FALSE:
The nervous system sends messages faster than the Endocrine System
True
These are the large branches that branch off of the cell body that RECIEVE information
Dendrites
The lowest part of the brain that comprises the pons, medulla, and cerebellum, that is responsible for basic life functions and movement
The Hindbrain
The "communication" system in your body that releases chemicals into your bloodstream to affect your behavior.
Endocrine System
Groups of neurons make up these
Nerves
This nervous system is made up of the brain and spinal cord.
Central Nervous System (CNS)
This is the part of the neuron that keeps it alive. It also analyzes the messaged the neuron receives.
Cell Body (Soma)
The tiny central part of your brain that the RAS extends out of.
The Midbrain
The types of chemicals that the glands of your endocrine system release are called:
Hormones
These types of neurons carry sensory (touch, hearing, vision, taste, smell) to the brain
Sensory
These nervous systems control various parts of the body and feed into the CNS
Peripheral Nervous Systems
This is the long part of the neuron that electric impulses travel down
Axon
This net-like system extends out of the midbrain into the forebrain and regulates behavior such as attention and sleep.
The Reticular Activating System (RAS)
The "master gland" of the endocrine system that controls all other glands
Pituitary Gland
These types of neurons carry messages to complete physical tasks such as catching a ball, or picking up a pen
Motor Neurons
This nervous system is responsible for functions that are not consciously directed, such as breathing, heartbeat, and digestion
Autonomic Nervous System
This is the thin later of fat that protects the axon
The myelin sheath
The wrinkly outermost layer of the brain that facilitates higher level thinking skills.
The Cerebral Cortex
The tiny part of your brain that regulates many parts of behavior such as:
Regulates body temperature
Storage of nutrients
Various aspects of motivation
Hunger
Thirst
Sexual behavior
Caring for offspring
aggression
and is part of the limbic system
The Hypothalamus
These types of neurons communicate between sensory and motor neurons
Interneurons
This Peripheral Nervous System controls voluntary movements via skeletal muscles
Somatic Nervous System
This is the period of time after a neuron fires its signal during which it cannot fire a signal again
Refractory Period
The part of the brain that facilitates communication between the two hemispheres
The Corpus Callosum
The "relay station" of the brain, that receives sensory information and transmits it to other parts of the brain and is part of the limbic system
Thalamus
The gap between neurons that chemical messages are sent between.
The synapse
