Add to cartWhat is the primary function of neurons in the nervous system?
Neurons are specialized cells that transmit electrical and chemical signals throughout the nervous system, enabling communication between different parts of the body.
input text value
What are the main structural components of a neuron?
The main structural components of a neuron are the cell body (soma), dendrites, and axon.
input text value
What role do dendrites play in neuronal communication?
Dendrites receive incoming signals from other neurons and convey this information to the cell body.
input text value
What is the function of the axon in a neuron?
The axon transmits electrical impulses away from the cell body to other neurons, muscles, or glands.
input text value
What is the myelin sheath and what is its function?
The myelin sheath is a fatty layer that surrounds the axon of some neurons, providing insulation and increasing the speed of signal transmission.
input text value
What are synapses?
Synapses are junctions between two neurons where communication occurs through the release and reception of neurotransmitters.
input text value
What is an action potential?
An action potential is a rapid, temporary change in the electrical charge of a neurons membrane, allowing the transmission of a signal along the axon.
input text value
What is the resting membrane potential of a neuron?
The resting membrane potential is the electrical charge difference across the neurons membrane when it is not actively transmitting a signal, typically around -70 millivolts.
