A. spinal meninx

B. cervical enlargement

C. spinal ganglion

D. spinal nerve

E. lumbar enlargement

The correct answer is D.

A dorsal and ventral root of each spinal segment unite to form a spinal nerve.

Explanation:

The spinal nerves (axon bundles) connect to each side of the spinal cord by a dorsal root and a ventral root. The afferent fibers enter through the dorsal root, while the efferent fibers exit through the ventral one. The cell bodies of the afferent neurons are concentrated in one dorsal root ganglion; those of efferent neurons, however, are found in the spinal cord itself, in the gray matter, and send axons through the dorsal root. Both roots unite in a single nerve when leaving the spinal cord, a nerve that, therefore, transmits information in both directions independently.

A dorsal and ventral root of each spinal segment unite to form a spinal nerve.

Explanation:

Spinal nerves are the mixed nerves emerging from the spinal cord and exiting at the intervertebral foramen.A dorsal and ventral root of each spinal segment unite to form a spinal nerve.

Proximal branches of the spinal nerve includes:

Distal branches :

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

i think the answer is 95 hope this
