The nervous system consists of the brain‚ spinal cord‚ and a complex network of neurons. This system is responsible for sending‚ receiving‚ and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let ’s take a look at the central nervous system. Central Nervous System The

Today‚ he was going to talk about his favorite part of the human anatomy: the brain. “Today is going to be exciting!” All of the students groaned.

Anatomy and physiology of the brain and spinal cord The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS

These neurodegenerative diseases are known to us as Alzheimer’s‚ fronto-temporal dementia‚ and Lewy bodies are where over time a build up of abnormal protein deposits in the brain cause the gradual change and damage to the neurons which will cause the shrinkage of the brain. Dementia is anything which affects the brain and the

The brain of an average human being contains 100 billion nerve cells or neurons. Billions more are found in other parts of the nervous system. Neurons come in all different sizes and shapes‚ but they all seem to be specialized to receive and transmit information. Neurons are made of neurons which contains chromosomes and genes‚ a cytoplasm which keeps the cells alive and a cell membrane that encloses the whole cell. Neurons are different from other cells because they have small fibers that branch
