Peripheral Nervous System Quiz

What is the structure of the peripheral nerves?

• Nerve fibers, connective tissue, and blood vessels

• Muscles, tendons, and ligaments

• Lymph nodes, spleen, and thymus

• Bone marrow, cartilage, and synovial fluid

Explain the function of the peripheral nerves.

• Regulate body temperature

• Produce hormones

• Digest food

• Transmit signals between the central nervous system and the rest of the body

Name two cranial nerves and their functions.

• 1. Auditory nerve - responsible for taste. 2. Facial nerve - responsible for hearing.

• 1. Trigeminal nerve - responsible for balance. 2. Vagus nerve - responsible for muscle movement.

• 1. Hypoglossal nerve - responsible for touch. 2. Spinal accessory nerve - responsible for smell.

• 1. Olfactory nerve - responsible for sense of smell. 2. Optic nerve - responsible for vision.

What is the role of the autonomic nervous system in the body?

• Manages the immune system

• Regulates conscious bodily functions

• Controls the skeletal muscles

• Controls involuntary bodily functions

How does the autonomic nervous system differ from the somatic nervous system?

• The autonomic nervous system controls voluntary movements, while the somatic nervous system controls involuntary bodily functions.

• The autonomic nervous system controls the brain functions, while the somatic nervous system controls the heart and lungs.

• The autonomic nervous system controls involuntary bodily functions, while the somatic nervous system controls voluntary movements and reflexes.

• The autonomic nervous system and somatic nervous system are the same and have no differences.

Explain the function of the sympathetic division of the autonomic nervous system.

• It regulates digestion and conserves energy

• It controls voluntary movements

• It is responsible for processing sensory information

• It prepares the body for stressful or emergency situations.

Describe the function of the parasympathetic division of the autonomic nervous system.

• Regulation of voluntary muscle movements

• Rest and digest functions

• Control of hormone release

• Fight or flight response

What are spinal nerves and nerve plexuses?

• Spinal nerves are part of the digestive system and nerve plexuses are related to the circulatory system

• Spinal nerves are found in the brain and nerve plexuses are found in the feet

• Spinal nerves are responsible for vision and nerve plexuses are responsible for hearing

• Spinal nerves are nerves that emerge from the spinal cord and nerve plexuses are networks of intersecting nerves that serve the motor and sensory needs of the limbs.

Explain the function of the autonomic nervous system.

• Controls the skeletal muscles

• Regulates conscious bodily functions

• Manages sensory perception

• Controls involuntary bodily functions

How do the sympathetic and parasympathetic divisions of the autonomic nervous system work together?

• They work together to maintain homeostasis in the body.

• They work together to shut down the body's functions.

• They work together to create chaos in the body.

• They work together to cause imbalance in the body.
