The nervous system is a system in the human body which is highly complex and divided into two main portions which are the peripheral nervous system and the central nervous system. Answer and Explanation:
Differentiate between the nervous systems of different animals Differentiate between the central and peripheral nervous systems List and describe the functions of the structural components of a neuron List and describe the four main types of neurons Describe the process of neurogenesis Compare the function...
The brain and the spinal cord are the central nervous system, and they represent the main organs of the nervous system. The spinal cord is a single structure, whereas the adult brain is described in terms of four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebe...
Name 4 functions of the Integumentary System. What layers of the skin constitute the cutaneous membrane? What substance is manufactured in the skin that plays a role in calcium absorption elsewhere in the body? What are the two main components of the nervous system?
What are the main components of the sympathetic nervous system? There are three major molecules secreted within the sympathetic nervous system –acetylcholine, epinephrine, and norepinephrine. Acetylcholine plays a major role in synaptic transmission of electrochemical signals from the presynaptic neurons. ...
Neurons are the principal components of the CNS. More than any other cell, neurons vary in size from location to location. Most neurons are very large cells (Figs. 14-4A and 14-36), measuring up to 40 μm in diameter, but their size can vary from 5 μm (granular layer of the cere...
The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral ...
The structure of a neuron consist of four main components dendrites, cell body also known as soma, synapse and axon. Dendrites collect signals coming in from other cells. The soma is responsible for assimilating signals coming in from the dendrites in order to create a signal traveling unidirecti...
Several layers of the human brain organization potentially bridging the two research streams, however, largely escape the current scientific focus. Among these layers, we believe, is the human brain lipidome. Lipids are the main components of brain tissue, comprising 78% of the dry weight of ...
Theimmune systemconsists of organs (bone marrow, spleen,thymus, and lymph nodes), cells (T cells; B cells; natural killer, NK, cells; monocytes/macrophages; and neutrophils), and messenger molecules (cytokines,chemokines, and prostaglandins). Thesecomponents of the immune systemare spread through...
