Which Of The Following Structures Is The Richest In Lipid Content?

Which Of The Following Structures Is The Richest In Lipid Content?

What does gray matter contain? The grey matter is mainly composed of neuronal cell bodies and unmyelinated axons. Axons are the processes that extend from neuronal cell bodies, carrying signals between those bodies.

Where are Neurosomas located? The neurosomas are the neurons’ cell bodies, which are of two types: posterior and anterior. The neurosoma of the posterior root is in the posterior ganglion- which forms the origin of the main cystic.

Which of the following branches of a spinal nerve has Neurosomas of only sensory neurons? Which of the following branches of a spinal nerve has the neurosomas of only sensory neurons? Posterior dorsal root.

What is a Cordlike organ composed of numerous?

a nerve is a cordlike organ composed of numerous nerve fibers (axons) bound together by connective tissue.

What does white matter contain?

nerve fibers
White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.

What is white and grey matter?

Overview. The tissue called “gray matter” in the brain and spinal cord is also known as substantia grisea, and is made up of cell bodies. “White matter”, or substantia alba, is composed of nerve fibers.

What is the function of dorsal root ganglion?

Structure and Function

The DRG is a group of cell bodies responsible for the transmission of sensory messages from receptors such as thermoreceptors, nociceptors, proprioceptors, and chemoreceptors, to the CNS for a response.

In what part of the body does the highest level of motor function occur?

One of the brain areas most involved in controlling these voluntary movements is the motor cortex. The motor cortex is located in the rear portion of the frontal lobe, just before the central sulcus (furrow) that separates the frontal lobe from the parietal lobe.

What are meninges quizlet?

What are meninges? Membranes of connective tissue that surround and protect the brain and spinal cord (CNS)

What is a bundle of nerve fibers within the white matter of the spinal cord called?

In each half of the spinal cord, white matter is divided into three major bundles, called funiculi. The dorsolateral sulcus marks the division between dorsal funiculus and lateral funiculus.

What is white matter quizlet?

What is white matter? White matter is composed of bundles of myelinated axons, which connect various gray matter areas of the brain to each other, and carry nerve impulses between neurons.

Why is white matter white quizlet?

Why is white matter white? The white matter of the CNS appears white because the majority of the nerve fibers in these regions are myelinated.

Why is grey matter important?

[6] The grey matter throughout the central nervous system allows enables individuals to control movement, memory, and emotions. Different areas of the brain are responsible for various functions, and grey matter plays a significant role in all aspects of human life.

What is brain matter called?

The central nervous system is made up of tissue known as grey matter and white matter. Grey matter (or gray matter) makes up the outermost layer of the brain and is pinkish grey in tone, hence the name grey matter.

What is not part of the brain?

The Correct Answer is Option 4 i.e Pinna. It is between then pons and spinal cord.

Why is white matter so called?

White matter is named for its relatively light appearance resulting from the lipid content of myelin. However, the tissue of the freshly cut brain appears pinkish-white to the naked eye because myelin is composed largely of lipid tissue veined with capillaries.

Why is it called dura mater?

Etymology. The name dura mater derives from the Latin for tough mother (or hard mother), a loan translation of Arabic أم الدماغ الصفيقة (umm al-dimāgh al-ṣafīqah), literally ‘thick mother of the brain’, matrix of the brain, and is also referred to by the term “pachymeninx” (plural “pachymeninges”).

What is the best description of the dura mater?

The tough outer layer of tissue that covers and protects the brain and spinal cord and is closest to the skull. The dura mater is one of the three layers that form the meninges.

Dura mater – the dura mater layer is the thickest, outermost layer. 2) Arachnoid mater – this layer has a weblike appearance. 3) Pia mater – this is the innermost layer and is very thin at only one cell thick.
