Peripheral nerves may refer to the head and torso. The peripheral nerves carry information from the spinal cord to the rest of the body as well as information to and from the brain.
Yes. The CNS (Central Nervous System) includes the brain and spinal cord, so everything within those two are considered within it also. All of the nerves on the outside of the CNS is called the PNS (Peripheral Nervous System).
Every area involving the brain, spinal cord, and nerves (central and peripheral nervous systems). So, essentially, just about everywhere in the body. It usually refer to the brain, spine, and musculoskeletal system, though.
Cranial nerves are named as such because they arise directly from the brain (cranium) rather than from the spinal cord. The term "cranial" is used to refer to structures within or connected to the skull, while "branial" is not a recognized term in anatomy.
The medical root word 'neuro' refers to the nerve.
Well, the spinal cord is the spinal cord, but when you are talking about it with the brain, they make up the central nervous system. There are also different spinal tracts and nerves depending on where they originate/end (ie spinocerebellar, corticospinal etc), so those can be referred to independently. In addition, there are meninges of the spinal cord, which are the connective membranes that enclose the spinal cord (which include the dura mater, the arachnoid mater, and pia mater and the spaces in between). So depending on which part you are talking about, they can be named individually, but the spinal cord is called the spinal cord as a whole. It's "Myel-"
Cranial nervesCranial Nerves only originate in the brain and carry messages to and from structures in the head and neck.
No, the actual stimulation of a nerve occurs at the level of the nerve itself, such as at the cell body or along the axon. Nerves are made up of bundles of axons that transmit signals to and from the brain or spinal cord to different parts of the body. Tracts, on the other hand, refer to bundles of axons within the central nervous system that carry specific types of information between different regions of the brain or spinal cord.
White matter is one of the two components of the central nervous system, and it consists mostly of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers. Grey matter contains neural cell bodies, unlike white matter, it does not and it mostly contains myelinated axon tracts. Tracts are bundles of fibers that connect to different parts of the central nervous system. A collection of related anatomic structures Roots receive information sent by neurons. Spinal nerves refer to a mixed of spinal nerves, which carry motor, sensory, and autonomic signals between the spinal cord and the body.
The medical root word 'meningo' refers to the meninges (coverings of the brain and spinal cord).
There is none to anyone else except that to which you assign. They refer to completely different things.
No the noun is "spine", "Spinal" is an adjective. However in medical parlance "a spinal" can refer to an injection (of anaesthetic) into the spine and in this single instance "spinal" is a noun.
