Spinal cord and Peripheral nerves

Front

What is contained inside the subarachnoid space?

Back

Cerebral Spinal Fluid (CSF) is contained in the subarachnoid space, providing cushioning and protection for the spinal cord and brain.

Front

What nerve innervates the hamstrings?

Back

The hamstrings are innervated by the Sciatic nerve, which is responsible for motor control of the muscles in the back of the thigh.

Front

What type of information travels through motor pathways?

Back

Motor pathways carry motor information, which is responsible for sending signals from the brain to muscles to initiate movement.

Front

What is the term for the collection of nerves that continue down the spinal canal after the spinal cord ends?

Back

The collection of nerves is known as the Cauda Equina, resembling a horse's tail, and it contains nerve roots that extend from the lower spinal cord.

Front

Which nerve innervates the triceps brachii muscle?

Back

The triceps brachii muscle is innervated by the Radial nerve, which allows for extension of the elbow.

Front

What is the function of the spinal cord?

Back

The spinal cord serves as a major conduit for information traveling between the brain and the rest of the body, facilitating reflex actions and sensory information processing.

Front

What are the two main types of nerves in the peripheral nervous system?

Back

The two main types of nerves are sensory nerves, which carry information from sensory receptors to the central nervous system, and motor nerves, which transmit signals from the central nervous system to muscles.

Front

What is the role of the cerebrospinal fluid (CSF)?

Back

Cerebrospinal fluid (CSF) cushions the brain and spinal cord, provides nutrients, and removes waste products.

Front

What is the difference between sensory and motor neurons?

Back

Sensory neurons transmit sensory information to the central nervous system, while motor neurons carry commands from the central nervous system to muscles.

Front

What is the anatomical term for the end of the spinal cord?

Back

The anatomical term for the end of the spinal cord is the Medullary Cone, which tapers off before the Cauda Equina begins.
