Spinal Cord

the part of the spinal cord that contains mylinated axons is the White matter portion.

horns

No, you don't. The sound is made by the air going through your lips and has no relationship to the vocal cords.

Diagnosis is usually accomplished through imaging of the cervical spine, with plain x rays, CT scans , and/or MRI imaging.

hemisection anywhere in spinal cord, and the result is a mixed sensory deficit.

you'll lose proprioception (two point discrimination) on the same side as the hemisection.

you'll lose pain and temperature sense on the side opposite of the hemisection.

depending on level in spinal cord, the effects will be different

multiple sclerosis

There is no joint between brain and spinal cord. The spinal cord is a mass of neurones that is situated in the backbone which feeds in to the brain via neurones.

the spinal cord is used to send messages around the body from the brain ie use left hand and arm to wave etc...

The spinal cord relays messages between the brain and body, making it possible to move and fell sensation.

gray matter is composed of neuron cells and is concentrated in the cerebral cortex and nuclei and basal ganglia.

white matter is composed ofneuron processes which form tracts connecting parts of the brain with each other and with the spinal cord.

Spinal nerves

Nerves. There are a lot of nerves going from the brain to the rest of the head: eyes, nose, mouth, tongue, cheeks, muscles, and so forth.

To connect with the rest of the body, all those nerves from the brain form a tight rope-looking organ called the spinal cord - so called because it runs down the inside hollow part of the spinal column.

Depends on the degree of injury.

A bruised cord can heal, and some function can return to a partially damaged cord. But a full recovery is rare, and unheard of for a complete separation.

Funiculi

that's a funny question, but i take it as my business to answer it- you would not continue to live. the medulla oblongata of the brain controls involuntary functions of the body, like respiration and heart beat. in absence of the brain, your system would malfunction and you would die.

in the absence of spinal cord, the reflexes of your body would slow down considerably, as the impulse would take longer time to be processed. for example, you would realize that the thing you are touching is hot after your finger tissues are burnt or something like that. in the absence of both, survival is impossible:)

nerves

our individual cells-neurons

conus medullaris

The medulla oblongata connects the brain to the spinal cord and controls involuntary actions. In comatose patients, it's the only part of the brain that functions.

human, monkey...

Your spinal cord doesn't have any particular 'casing', but it does run down the middle of your neck muscles and between your back muscles, then continuing through to your buttocks muscles.

So generally, just a series of different muscles, but it doesn't have any constant surrounding tissue of any form.

The dura mater in the brain is fused to the periosteum vs in the spinal cord the epidural space is in between the dura mater and the intervertebral canal.
Three fibrous membranes that surround the brain and spinal cord to protect the central nervous system. The pia mater, a very thin membrane, adheres to the surface of the brain and spinal cord. The subarachnoid space, containing cerebrospinal fluid, separates the pia mater from a second membrane, the arachnoid. Around the brain, fine filaments connect these two membranes, which are believed to be impermeable to fluid. The third membrane, the dura mater, is strong, thick, and dense. It envelops the arachnoid, covers the inside of the skull, and surrounds and supports the large venous channels carrying blood from the brain. Several septa divide it and support different parts of the brain. In the spine, the dura mater and the arachnoid mater are separated by the subdural space; the arachnoid and pia mater are separated by the subarachnoid space. The extradural space (between the dura mater and the wall of the vertebral canal) is the site of epidural anesthesia (see anesthesiology).

Close - poliomyelitis is a viral infection affecting the gray matter of the spinal cord.
