The nervous system is part of the human body that coordinates its actions. It transmitting signals to different parts of the body. The nervous system detects environmental changes. These changes affect the body and then works with the endocrine system to respond to such events. Nervous tissue first developed in worm organisms around 550 […]
ganglion cells and their support cells contain the optic nerve. The optic nerve receives a visual signal in orbit and moves back and forth through the visual channel. Then it leads to fiber. At this point, the fibers from the temporal fields are broken up. The fibers then pass through optical paths. Most of the […]
The brain controls the capability to think, speak, feel, see, hear, remember, walk and many other things. It controls even your breath. The brain is a spongy mass of carrying tissues and nerves connected to the spinal cord. Few nerves in the brain go direct to the eyes, ears and other parts of the […]

Lymph nodes (mediastinum) are small round organs of the lymphatic system that support the proper functioning of the immune system. They help the body fight infection by filtering foreign lymphatic particles, a transparent or whitish fluid that consists of white blood cells.

Your cardiovascular system consists of the heart and blood vessels. There are three kinds of blood vessels in the circulatory system: veins, capillaries, and arteries. Arteriovenous malformation defects (AVM) are defects in the blood vessels of the circulatory system. Read below for arteriovenous malformation brain A developmental defect is an abnormal combination of veins […]
The myocardium is the thick, middle layer of the heart and is composed of cardiac muscle. Cardiac muscle is very unique because it possesses the characteristics of skeletal muscle and smooth muscle. Skeletal muscle controls. The muscles of the body. The myocardium acts on its own, with no conscious effort. Myocardium consists of thousands of […]
Many critical discoveries have underlined the importance of astrocytes in establishing a synaptic connection in the developing brain. In this article, we review the key findings of astrocytes function and elimination of synapses. First, we summarize our current structural and functional understanding of astrocytes in the synapse. Next, we will discuss the cellular and […]
The sebaceous glands are a tissue that releases oil in the skin of a mammal. When a piece of the epidermis is examined under a microscope, we see a hair follicle that pierces the surface of the skin to the subcutaneous layer. Inside there is a secretory sebaceous tissue. Waxy oil, which is excreted into […]
The parasympathetic nervous system function is responsible for stimulating “rest and digestion. The feeding and reproduction” activities that occur when the body is resting, especially after eating, including sexual arousal, drooling, tearing (tears), urination and defecation. The nerve fibers of the parasympathetic nervous system arise from the central nervous system. Specific nerves include several […]
Cerebrospinal fluid is a clear, colorless transcellular fluid, in the ventricular system, and the central canal of the spinal cord. It also fills some gaps in subarachnoid space, known as subarachnoid cisterns. The four ventricles, four lateral, a third, and a fourth ventricle, all contain choroid plexus that produces cerebrospinal fluid. The third ventricle lies […]
A neurotransmitter is a chemical substance produced in the body. It is responsible for a process called synaptic transmission or neurotransmission. In this article, we will discuss the mechanism of neurotransmission, the classification of neurotransmitters and several clinical remarks on disorders related to the excessive and lack of some neurotransmitters function. The neurotransmitters […]
