Anatomy of the Spinal Cord and Peripheral Nervous System Quiz

Ventral horn is the region of the spinal cord responsible for motor functions, housing cell bodies of motor neurons.

The primary function of the peripheral nervous system is to control voluntary movements by transmitting signals between the central nervous system and the body's muscles and glands.

A nerve is a bundle of nerve fibers within the peripheral nervous system, transmitting signals between different parts of the body.

The dura mater is a protective membrane that surrounds the spinal cord, providing cushioning and support.

The autonomic nervous system controls involuntary functions, including muscle contractions, regulating bodily functions without conscious effort.

The cauda equina is the collection of spinal nerves that extends inferiorly from the end of the spinal cord.

Acetylcholine is a neurotransmitter commonly associated with transmitting signals in the peripheral nervous system.

The brachial plexus is the spinal nerve plexus primarily responsible for innervating the muscles of the upper limbs.

Epinephrine is the neurotransmitter associated with the fight-or-flight response in the sympathetic division of the autonomic nervous system.

The central canal is the space within the spinal cord that contains cerebrospinal fluid.

The dorsal root ganglion is responsible for transmitting sensory information from the peripheral nervous system to the brain.

White matter in the spinal cord primarily functions in transmitting nerve impulses, serving as a communication pathway.

The ventral horn of the spinal cord is responsible for coordinating reflexes involving skeletal muscles.

The correct sequence of events in a spinal reflex arc is stimulus, sensory neuron activation, motor neuron response, and effector reaction.

The cell bodies of motor neurons in the spinal cord are located in the gray matter.

The ventral horn of the spinal cord is responsible for transmitting motor signals to skeletal muscles.

The arachnoid mater in the spinal cord functions in cushioning and shock absorption, providing additional protection.
