5.1 The Nervous System Flashcards
What is the function of the nervous system?
The nervous system coordinates the body’s response to internal and external stimuli
What are the main components of the nervous system?
The brain, spinal cord, and nerves
What is a neuron?
A specialized cell that carries electrical impulses throughout the body
What is the role of sensory neurons?
Sensory neurons transmit information from sensory receptors to the central nervous system
What is the role of motor neurons?
Motor neurons transmit information from the central nervous system to muscles or glands
What is the role of interneurons?
Interneurons connect sensory neurons and motor neurons in the central nervous system
What is a synapse?
A junction between two neurons where information is transferred via neurotransmitters
What is the process of synaptic transmission?
An electrical signal is transmitted across the synapse using neurotransmitters, which bind to receptors on the next neuron
