1. What structure is referred to as the conus medullaris?

Esophagus

Conus Medullaris

Liver lobe

Knee cap

The conus medullaris is the tapered end of the spinal cord where it ends around the first or second lumbar vertebra in the lower back. It is responsible for transmitting neural signals between the brain and the lower extremities.

2. What is the function of the conus medullaris?

Description:
• Tapered inferior end of spinal cord

Regulates body temperature.

Controls voluntary movements of the body.

Stores cerebrospinal fluid.

The conus medullaris is responsible for being the tapered inferior end of the spinal cord, contrary to the incorrect options provided.

Explanation

The conus medullaris is responsible for being the tapered inferior end of the spinal cord, contrary to the incorrect options provided.

3. What is the tapered inferior end of the spinal cord referred to as?

Cauda equina

Filum terminale

Conus medullaris

Spinal nerve roots

The conus medullaris is the tapered inferior end of the spinal cord, while the cauda equina refers to the collection of spinal nerve roots below the spinal cord. The filum terminale is a thin strand of fibrous tissue at the end of the spinal cord, and spinal nerve roots are bundles of nerves emerging from the spinal cord.

Explanation

The conus medullaris is the tapered inferior end of the spinal cord, while the cauda equina refers to the collection of spinal nerve roots below the spinal cord. The filum terminale is a thin strand of fibrous tissue at the end of the spinal cord, and spinal nerve roots are bundles of nerves emerging from the spinal cord.

4. What is the name of the large bundle of dorsal and ventral roots for spinal nerves located below the L2 vertebral level in the vertebral canal?

Spinal cord

Cauda equina

Dorsal root ganglion

Ventral horn

The cauda equina is a large bundle of spinal nerves and nerve roots that extend below the level of the spinal cord, resembling a horse's tail in appearance.

Explanation

The cauda equina is a large bundle of spinal nerves and nerve roots that extend below the level of the spinal cord, resembling a horse's tail in appearance.

5. What is the structure known as the cauda equina?

Pituitary gland

Cauda equina

Central nervous system

Sacroiliac joint

The cauda equina is a bundle of spinal nerves and spinal nerve rootlets, which can be found within the lumbar spinal canal below the spinal cord.

Explanation

The cauda equina is a bundle of spinal nerves and spinal nerve rootlets, which can be found within the lumbar spinal canal below the spinal cord.

6. What is the description of the cauda equina?

Location:
• Vertebral canal inferior to L2 vertebral level Description:
• Large bundle of dorsal and ventral roots for spinal nerves below L2 Comment:
• Latin: cauda equina = horse tail

Located in the thoracic region of the spine

Latin: cauda equina means lion's tail

Consists of just ventral roots for spinal nerves

The cauda equina is actually located inferior to L2 vertebral level, consists of both dorsal and ventral roots, and the term 'cauda equina' translates to 'horse tail' in Latin.

Explanation

The cauda equina is actually located inferior to L2 vertebral level, consists of both dorsal and ventral roots, and the term 'cauda equina' translates to 'horse tail' in Latin.
