Nervous Tissue


The embryonic origin of all neural tissue?

Neural tissue originates from the ectoderm layer of the developing embryo. This layer gives rise to the neural tube, which later differentiates into the central nervous system (brain and spinal cord) and the peripheral nervous system. Neuromesodermal progenitors are involved in the development of both neural and mesodermal tissues during embryonic development.


Where do Preganglionic neurons develop from?

Preganglionic neurons develop from the neural tube during embryonic development. They are part of the autonomic nervous system and transmit signals from the central nervous system to the autonomic ganglia, where they synapse with postganglionic neurons.


What are the cables of the nervous system called?

Information from the peripheral nervous system is carried to the central nervous system by neural cables called nerves. The work groups that neurons cluster into are known as neural networks.


What is the function of neural arches?

They act as the hearts of annelids (segmented worms)


Almost fifty percent of the volume of neural tissue in the central nervous system is made up of what?

Almost fifty percent of the volume of neural tissue in the central nervous system is made up of glial cells. Glial cells provide support and insulation to neurons, help maintain homeostasis, and play a role in immune response in the brain and spinal cord.


What is Central and peripheral Neural Mechanism of Emotion?

Central neural mechanisms of emotion involve brain regions such as the amygdala and prefrontal cortex, which control emotional responses and regulation. Peripheral neural mechanisms involve the autonomic nervous system and hormonal processes that influence physiological changes in response to emotions, like changes in heart rate or sweating. Together, these mechanisms work in concert to generate and regulate emotional responses in the brain and body.


What is a neural tube?

The neural tube is the part of the development of the central nervous system in a developing embryo. What is pretty amazing about this is that within the first 4 weeks of development from conception, the entire framework of the central nervous system will have finished forming! Around day 18, the neural plate appears at the midline of the thickening of the ectoderm, the outermost layer of the germinal sac. Essentially what happens over the next couple of days is that the neural plate forms a depression, which eventually is pushed down and separated from the original cell layer by the fusion of the neural crests, resulting in the formation of a neural tube - this is rather hard to explain without a proper diagram!


What is a neural vessicle?

These are the vessicles in the terminal button that contain the neurotransmitters.


What is formed from neural crest cells?

Neural crest cells give rise to various cell types including neurons, glial cells, melanocytes, and cells of the peripheral nervous system. They also contribute to structures such as bones, cartilage, and connective tissue in several regions of the body.


What does neural mean?

Neural means "of or relating to the nerves, neurons, or nervous system".


What is the neural tube formed by the fusion of?

In the embryo the neural tube forms the central nervous system in the fetus, which is the brain and spinal cord. The reason pregnant women are given folic acid supplementation is to help prevent neural tube defects, which can range from fairly benign all the way to anencephaly (where the baby is born without a brain).
