Front

What are AFFERENT Neurons?

Back

Afferent neurons are sensory neurons that transmit impulses to the Central Nervous System (CNS).

Front

What part of the reflex arc monitors body conditions?

Back

The sensory neuron monitors body conditions in the reflex arc.

Front

What part of the reflex arc stimulates muscles and nerves?

Back

The motor neuron stimulates muscles and nerves in the reflex arc.

Front

Where are spinal reflexes integrated?

Back

Spinal reflexes are integrated in the spinal cord, while cranial reflexes are integrated in the brain stem.

Front

Which part of the spinal cord contains cell bodies from somatic motor neurons?

Back

The anterior gray horn contains cell bodies from somatic motor neurons.

Front

Define sensory neuron.

Back

A sensory neuron is a type of afferent neuron that carries sensory information from the body to the CNS.

Front

What is the role of the integration center in a reflex arc?

Back

The integration center processes the sensory information and determines the appropriate response.

Front

What is the function of the effector in a reflex arc?

Back

The effector is the muscle or gland that carries out the response to the stimulus.

Front

Differentiate between spinal reflexes and cranial reflexes.

Back

Spinal reflexes are processed in the spinal cord, while cranial reflexes are processed in the brain.

Front

What is the function of the motor neuron in a reflex arc?

Back

The motor neuron transmits impulses from the integration center to the effector.
