How does the structure of the nervous system relate to its function?
The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.
How does the nervous system help the body function?
The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
Which organ is part of our nervous system?
The brain and the spinal cord are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.
What is nervous system disorder?
Brain and nervous system problems are common. These neurological disorders include multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, epilepsy, and stroke, and can affect memory and ability to perform daily activities.
What is nerve structure?
A nerve is the primary structure of the peripheral nervous system (PNS) that encloses the axons of peripheral neurons. A nerve provides a structured pathway that supports neuron function. A nerve consists of many structures including axons, glycocalyx, endoneurial fluid, endoneurium, perineurium, and epineurium.
What is the most important part of the nervous system?
The brain and the spinal cord make up the central nervous system. The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.
