Brainstem function Location & structures| Main function
The brain stem is the area of the brain that connects the brain to the spinal cord. It consists of the midbrain, medulla, and bridge. Motor and sensory neurons travel through the brainstem to allow signals to be transmitted between the brain and the spinal cord. Most cranial nerves are in the brainstem. Read below […]
What does bone marrow do | Bone marrow and the immune system
Each parent should know about bone marrow and the immune system, preparing for a child’s blood transplant and bone marrow transplant (BMT). main points Bone marrow is soft tissue inside the bone that produces blood cells. The bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are made in the bone marrow […]
Metabolism and how does it work in the human brain
The brain uses up to 20% of the energy consumed by the human body, more than any other organ. In humans, blood glucose is the main source of energy for most cells and is critical to normal function in many tissues, including the brain. The human brain consumes about 60% of blood glucose on […]
Eye functions and Sight problems
The eyes are the organs of the visual system. They provide visions to the bodies, the ability to receive and process visual details, and also enable several photo response functions that are independent of the vision. The eyes detect light and transform it into electrochemical impulses in neurons. In elevated organisms, the eye is […]
Optic nerve function & Structure
The optic nerve is located in the back of the eye. It is also called the second cranial nerve. This is the second of several cranial nerve pairs. The task of the optic nerve is to transmit visual information from the retina to the brain’s viewing centers by means of electrical impulses. Optic nerve […]
Sebaceous glands functions and development
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 […]
Dermis function & Dermal papillae
NoThe dermis or corium is a layer of skin between the epidermis (with which it forms the skin) and the subcutaneous tissue, which consists mainly of dense irregular connective tissue and absorbs the body from stress and tension. It is divided into two layers, the surface area adjacent to the epidermis is called the papillary […]
Carpal bones mnemonic and major functions
The bones of the carpal are eight small bones that form the wrist and that joins the hand with the forearm. In human anatomy, the main role of the carpal bone is to facilitate effective hand positioning. In the tetrapods, the carpal is the only cluster of bones in the wrist between the radius […]
Synapse neuron understanding working in the human brain
Synapse neuron is basically electrical devices. There are many channels in the cell membrane (the boundary between the cell inside and outside) that allow the flow of positive or negative ions into and out of the cell. Usually, the inside of the cell is more negative than outside; neurologists say that the inside is […]
Nervous tissue function and Types of neurons By structure
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 […]
