Nervous system and Endocrine system

Nervous system

The Nervous system uses electricity to gather, process, and respond to information about the environment.

Nervous cell

The unique structure of the nerves makes them special in carrying and receiving electrical impulses from all over the body. Glaze cells support the nerves, protecting and isolating them by being around them.

All nerves have certain characteristics in common, such as cells, nerves, and axons. These structures are very important for the conduction of surges, electrical currents, which allow the nerves to communicate with each other.

Function of Nerves

Nerves are specialized, depending on their function:

1. The sensory nerve carries impulses from sensory organs, such as the eye or ear.
2. The motor nerve carries the surge from the muscles and glands.
3. The subconscious conducts current between the conductor and the sensory nerve as well as between the other subconscious.

In the resting nerve, the breakdown of ions in the cell is regulated by the sodium-potassium pump. If the nerves receive a long signal, the resting kinetic potential changes, an emitting momentum is called an active kinetic epoch, once the emitting moment begins and it moves downward until it reaches the axon.

Part of the nervous system

The Nervous system is made up of two parts: the central Nervous system (CNS) and the peripheral Nervous system (PNS).

The CNS is made up of the brain and spinal cord. The signals given to the body are generated in the brain and the spinal cord connects the rest of the body's nerves with the brain.

PNS can be divided into two parts:

1. The somatic nervous system (SNS) regulates voluntary actions such as muscle movements. It also controls reflex actions such as pulling your hand away from the hot surface of the stove.

2. The autonomic nervous system (ANS) controls actions that are not performed in the waking state and has two parts that are opposite to each other: sympathetic and parasympathetic nervous system. The sympathetic nervous system prepares the body for my-ya-parts response, while the parasympathetic Nervous system is active during periods of rest.

Endocrine system

Like the Nervous system, the Endocrine system is a regulatory system. However, instead of using electrical current for signal, it produces and uses chemical signals called Endocrine glands, which move in the bloodstream as well as regulate the activity of cells and organs.

Normal Endocrine and glands

Endocrine	Occurs in the gland	Part
Thyroid gland	Thyroid	Regulation of metabolism
Adrenal	Adrenal gland	Involvement in the fight or parts of the fight
Cortisol	Adrenal gland	Involvement in fight or parts response, regulation of metabolism and response for protection
Estrogen	The egg	Development of sexual and reproductive organs mainly in females
Testosterone	Sperm, sometimes in the adrenal gland or ovary	Development of sexual and reproductive organs mainly in males
Insulin	Pancreas	Regulation of blood sugar, storage of fats
Glucagon	Pancreas	Regulation of blood sugar

Regulation of Endocrine glands

The Endocrine system is regulated by the negative response that works to maintain the isotope system. This is how the concentration of the hormone, and how it affects other systems of the body, is controlled.

For example, blood sugar is regulated by insulin and glucagon, a hormone produced by the pancreas.

When blood sugar levels rise, the pancreas releases insulin, which lowers blood sugar levels. This prevents the blood sugar from going high.

When blood sugar concentrations drop, the pancreas releases insulin, which breaks down glycogen and releases blood sugar. This brings the blood sugar back to normal.

Common mistakes and misconceptions

#1. When nerves are referred to as known Nervous system cells, they are not the only ones! In fact, glacial cells are about 10 times larger than nerves, the glacial cell supports the nerves, guides them, protects them and provides the nerve fibers around the axons.

#2. Hormones are not just part of the reproductive system. There are hormones for the reproductive system such as testosterone, estrogen, most of the hormones are not included in the reproductive system or are not regulated by them. Most hormones regulate bodily functions, such as hunger or drowsiness.

#3. Both the Endocrine system and the Nervous system regulate, but there are a few major differences. The endocrine system uses chemical signals (hormone produced by the glands) while the Nervous system uses electrical impulses. The Nervous system carries messages quickly because the nerves are connected to each other, but their function is short-lived. The Endocrine system carries messages slowly because the hormone passes through the bloodstream, but their response lasts longer.
