AP 22-23 Bio Unit 5 Review

Front

What type of neuron receives signals from sensory organs?

Back

Sensory neurons receive signals/stimuli from the eyes, ears, nose, skin, or tongue and transmit this information to other neurons.

Front

What is the function of motor neurons?

Back

Motor neurons signal digestive glands to release enzymes, muscles to contract, or cause other actions in the body.

Front

Where are interneurons primarily located and what is their role?

Back

Interneurons are present in the spinal cord or brain and receive signals from sensory neurons or communicate signals to motor neurons.

Front

What type of cells are produced to provide a faster immune response upon secondary exposure to an antigen?

Back

Memory cells are produced to initiate a faster response against secondary exposure to an antigen.

Front

What is released into the synaptic cleft to act as a signaling molecule?

Back

Neurotransmitters are released into the synaptic cleft and act as signaling molecules.

Front

Define sensory neurons.

Back

Sensory neurons are responsible for transmitting sensory information from sensory organs to the central nervous system.

Front

Define motor neurons.

Back

Motor neurons transmit signals from the central nervous system to muscles or glands to elicit a response.

Front

What is the role of interneurons in the nervous system?

Back

Interneurons connect sensory and motor neurons and are involved in reflexes and communication within the central nervous system.

Front

What are memory cells and their significance in the immune system?

Back

Memory cells are a type of immune cell that remembers past infections and enables a quicker response upon re-exposure to the same pathogen.

Front

What is a neurotransmitter?

Back

A neurotransmitter is a chemical messenger that transmits signals across a synapse from one neuron to another.
