Nervous System and Homeostasis
These specialized cells make up the nervous system.
What are neurons?
The CNS is made up of these two main parts.
What are the brain and spial cord?
The PNS consists of all nerves outside of the system.
What is the central nervous system?
The three main types of neurons.
What are sensory neurons, motor neurons. and interneurons?
This type of neuron carries signals from sense organs to the CNS.
What are sensory neurons?
This is the primary role of the nervous system in maintaining homeostasis.
What is controlling body functions and responsible to stimulation?
This is the brains largest region, responsible for intelligence an voluntary activities.
What is the cerebrum?
The PNS has these two main divisions.
What are the sensory and motor divisions?
The structure that carries impulses way from the cell body.
What is the axon?
This type of neuron transmits signals from the CNS to the muscles and glands.
What are motor neurons?
The nervous system is divided into these two main parts.
What are the Central and Peripheral system?
This connects the brain to the spinal cord and regulates heart rate, breathing, and swallowing,
What is the Brainstem?
The motor division is split into these two systems.
What are the somatic and autonomic nervous system?
This lipid layer speeds up impulse transmission along an axon.
What is the myelin sheath?
These neurons connect sensory and motor neurons.
What are interneurons?
The fluid that protects the CNS and allows for nutrient exchange.
What is cerebrospinal fluid?
This part coordinates muscle movements and processes body position information.
What is the cerebellum?
This system regulates involuntary actions like heartbeat and digestion.
What is the autonomic nervous system?
The gap between two neurons where neurotransmitters are released.
What is the synapse?
The electrical charge difference across a resting neuron's membrane is called this.
What is the resting potential?
This brain region regulates hunger, thirst, fatigue, and body temperature.
What is hypothalamus?
The part of the brain that acts as a relay station for sensory information.
What is the thalamus?
These two autonomic nervous system subdivisions have opposite effects on organs.
What are the sympathetic and parasympathetic nervous system.
The type of ion pump responsible for maintaining resting potential i neurons.
What is the sodium-potassium pump?
The minimum stimulus required to trigger a nerve impulse.
What is the threshold?
