Nervous System Basics
This complex network of nerves and cells transmits signals between different parts of the body.
What is the nervous system?
These specialized cells transmit electrical and chemical signals.
Neurons
A change in the environment that triggers a response is called this.
Stimulus
The CNS consists of the brain and this structure.
Spinal Cord
This part of the PNS controls voluntary muscle movements.
What is the Somatic Nervous System?
The two main parts of the nervous system are the CNS and this.
Peripheral Nervous System (PNS)
This part of a neuron processes information.
Cell body
A bright light or a loud sound are examples of this type of stimulus.
External Stimulus
This part of the brain controls thinking, memory, and voluntary movements.
Cerebrum
The two subdivisions of the Autonomic Nervous System are the sympathetic and this system.
Parasympathetic nervous system
The nervous system helps maintain this internal balance.
Homeostasis
These branch-like structures receive signals from other neurons.
Dendrites
Hunger and a full bladder are examples of this type of stimulus.
Internal Stimulus
This part of the brain regulates balance and coordination.
Cerebellum
This part of the PNS controls involuntary actions like digestion and heart rate.
Autonomic Nervous System?
The nervous system controls both voluntary and these types of actions.
What are involuntary actions?
This long extension of a neuron transmits signals to other cells.
Axons
The body's reaction to a stimulus is called this.
This part of the brainstem regulates breathing and heartbeat.
Brainstem
The "rest and digest" response is controlled by this part of the Autonomic Nervous System.
Parasympathetic nervous system
Main organs of the nervous system may include... (List 4)
Brain, Spinal Cord, Nerves, and Ganglia (clusters of nerve cells bodies that help relay information)
The three types of neurons are sensory, motor, and these.
Interneurons
Pulling your hand away from a hot stove is an example of this type of response.
Involuntary Response
The spinal cord is protected by these bony structures.
Vertebrae's
The "fight or flight" response is controlled by this part of the Autonomic Nervous System.
