Nervous System Exam

What is the main function of the nervous system?

• Regulate body temperature

• Produce hormones

• Digest food

• Transmit signals between different parts of the body

Explain the difference between the central nervous system and the peripheral nervous system.

• The central nervous system is located in the arms and legs, while the peripheral nervous system is in the head and torso.

• The central nervous system is made up of nerves, while the peripheral nervous system is composed of the brain and spinal cord.

• The central nervous system includes the brain and spinal cord, while the peripheral nervous system consists of all the nerves outside of the central nervous system.

• The central nervous system is responsible for motor functions, while the peripheral nervous system controls sensory functions.

How does a neuron transmit signals?

• By sending smoke signals

• Through photosynthesis

• Via telepathy

• Through an electrochemical process involving depolarization, action potential, and neurotransmitter release.

What are the main parts of a neuron?

• nucleus, cytoplasm, and cell membrane

• cell body (soma), dendrites, and axon

• mitochondria, Golgi apparatus, and endoplasmic reticulum

• ribosomes, lysosomes, and vacuoles

Describe the process of synaptic transmission.

• Synaptic transmission is a passive process that does not require neurotransmitter binding.

• Synaptic transmission occurs through direct electrical connections between neurons.

• Synaptic transmission involves neurotransmitter release, diffusion across the synaptic cleft, binding to receptors, and signal propagation in the postsynaptic neuron.

• Synaptic transmission involves the release of hormones instead of neurotransmitters.

What is the role of neurotransmitters in the nervous system?

• Neurotransmitters are produced by the skeletal system

• Neurotransmitters play a crucial role in regulating various functions such as mood, memory, muscle movement, and more.

• Neurotransmitters are only involved in regulating body temperature

• Neurotransmitters have no role in the nervous system

Explain the fight or flight response in terms of the nervous system.

• The fight or flight response is controlled by the parasympathetic branch of the autonomic nervous system.

• The fight or flight response is a voluntary reaction initiated by the brain.

• The fight or flight response is only triggered by external stressors.

• The fight or flight response is controlled by the sympathetic branch of the autonomic nervous system.

What are the main divisions of the autonomic nervous system?

• Sympathetic division and parasympathetic division

• Voluntary division and involuntary division

• Central division and peripheral division

• Motor division and sensory division

Discuss the functions of the cerebrum in the brain.

• The cerebrum functions include controlling the endocrine system and hormone production.

• The cerebrum functions include storing long-term memories and emotions.

• The cerebrum functions include regulating heart rate and digestion.

• The cerebrum functions include thinking, perceiving, planning, understanding language, controlling voluntary movements, and housing sensory and motor areas.

How does the nervous system coordinate voluntary and involuntary actions?

• Through the skeletal and muscular systems.

• Through the circulatory and endocrine systems.

• Through the digestive and respiratory systems.

• Through the somatic and autonomic nervous systems.
