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 […]
Electrical properties are one of the essential things that enable the heart to process. These electrical properties are accountable for the regulation of heart rate and rhythm. How the heart works step by step through the cycle of the heart The heart cycle covers many different things, enabling the heart to work. During […]
Take a deep breath. Now blow it up slowly. The air that you have taken or inhaled while breathing is filled with oxygen, which your body needs to generate energy for cellular activities. The air blown or exhaled is filled with carbon dioxide, which is a waste in the human body and removed during exhalation. […]
The primary visual cortex is the most studied area of vision in the brain. In mammals, it is located in the posterior pole of the occipital lobe and is the simplest, earliest cortical field of view. It is highly specialized in processing information about static and moving objects and is perfectly suited for pattern recognition. […]
Ribosomes are a cellular structure that produces a protein. The protein is needed for many cellular functions, such as repairing damage or managing chemical processes. Ribosomes can be found floating in the cytoplasm or attached to the endoplasmic reticulum. The location of ribosomes in the cell determines the type of protein produced. If the ribosomes […]
The earlobe is also known as the earlobe and is most often referred to as the ear. This is the most visible part of the auditory system. The auricle consists of the skin of straight cartilage and is held in place by the muscles and ligaments. The shape may vary depending on the type of body […]
Human hands are complicated and delicate structures that contain 27 bones. The muscles and joints in the hand allow for strong, precise and agile movements, but are susceptible to injuries. There are many different causes and types of pain in the palm of the hand near the thumb. Hand pain can come from different […]
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 […]
Rugby is one of the most physical sports. In the international arena, the top of the sport lies in the Rugby World Cup. Other tournaments such as Tri-Nations (including South Africa, New Zealand and Australia), Six Nations (including England, Ireland, Scotland, Wales, Italy, and France) and the Heineken Cup are other tournaments that enjoy great […]
The cerebellum is located behind the upper part of the brain stem (where the spinal cord is in contact with the brain) and consists of two hemispheres (halves). It receives information from sensory systems, the spinal cord and other parts of the brain, and then regulates motor motions. The cerebellum coordinates voluntary movements such […]
The snail is the most critical element of the inner ear. It is divided into three chambers filled with liquid, called scale, that move spirally around the bone core. In the cochlea channel, there is the organ of Corti, who receives the sound. The Corti organ consists of supporting cells and many thousands of sensory […]
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. Lymphrate also contains a type of white blood cells called lymphocytes that help […]
The smooth endoplasmic or smooth ER reticulum is an organelle that occurs both in animal cells and in plant cells. The organelle is a subunit in a cell that has a specialized function. The main function of a smooth ER is the production of cellular products such as hormones and lipids. It also distributes these […]
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 nervous tissue function in the human brain is the most inspiring and fascinating organ in the human body. Every memory you have and every emotion you will ever experience is an extraordinary result of evolution. The nervous system is the driving force of the brain, consisting of nervous tissue. It is divided into […]
