Front

What is cerebrospinal fluid?

Back

Cerebrospinal fluid is a clear liquid that surrounds the brain and spinal cord, providing cushioning and serving a role in diagnostics.

Front

What are proprioceptors?

Back

Proprioceptors are specialized sensory receptors that monitor body position and movement, allowing for balance and spatial awareness.

Front

Where are Schwann cells located?

Back

Schwann cells are located in the peripheral nervous system (PNS) and are responsible for the myelination of peripheral nerves.

Front

What initiates an action potential in a neuron?

Back

An action potential in a neuron is initiated by a chemical signal from another cell, which causes a change in membrane potential.

Front

What is the role of the thalamus in the brain?

Back

The thalamus relays sensory information and processes it before sending it to the appropriate areas of the brain.

Front

Define interstitial fluid.

Back

Interstitial fluid is the fluid that fills the spaces between cells in tissues, providing a medium for nutrient and waste exchange.

Front

What are chemoreceptors?

Back

Chemoreceptors are sensory receptors that respond to chemical stimuli, such as changes in blood pH or the presence of specific molecules.

Front

What is the function of thermoreceptors?

Back

Thermoreceptors are sensory receptors that detect changes in temperature, allowing the body to respond to thermal stimuli.

Front

What is the central nervous system (CNS)?

Back

The central nervous system consists of the brain and spinal cord, serving as the main control center for processing information.

Front

What is the peripheral nervous system (PNS)?

Back

The peripheral nervous system includes all the nerves outside the central nervous system, connecting the CNS to the limbs and organs.
