What are 3 functions of the nervous system? Detect changes inside and outside of the body make decisions based on the info they receive…
DFQ #A. Explain in your own words everything you have learned about pain starting out with a definition. Pain is an unpleasant sensory and emotional experience caused by intense stimuli. Pain can range from dull, to extremely sharp, and even emotional. Pain can helps us survive by warning our bodies of potential danger, or can be an indicator that something is wrong.…
It can spread information with the help of neurons, who pass information from one neuron to the next. There are two different pathways in the nervous system the afferent and efferent nerves. The afferent nerves pass information from the brain and spinal cord, while the efferent nerves have to do with the muscles in our body. It also contains two divisions called the central or peripheral nervous system. The central nervous system contains only the brain and the spinal cord while the peripheral nervous system connects both the brain and the spinal cord to other parts of the body.…
which are all things that our body must do to stay alive. The nervous system contains billions of neurons that are in constant touch with each other for the purpose of monitoring and regulating your internal and sensory functions. The central…
Bones are made of 25% water and 75% solids. the skeletal system protects and shields soft delicate organs so we are more resilient. Nervous system - The nervous system is basically the computer system of the body, by which every function of the human body is controlled. The brain also stores information which we learn over our lifetime much…
The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract. The human digestive system is the organ system responsible for extracting nutrients from consumed food items and absorbing the nutritional molecules into the bloodstream. Doing this requires breaking food into smaller pieces mechanically and chemically, so that nutritional molecules are isolated and can be absorbed. This process involves the help of the muscular system.…
It keeps, perceives and presents the information accordingly. • The Peripheral Nervous System is the section of the nervous system which comprises of “nerves and ganglia in the exterior of the brain and spinal cord”en. m Wikipedia). Their key role is to link the Central Nervous System, all parts of the body and it is an essential communication system back and forth the spinal cord and the brain as well as the entire body.…
The brain is a very complex organ made up of nervous tissue. According to Liliefend et al., the most important cell within this tissue is the neuron which receives and generates electrical impulses. These impulses travel through the neurons and trigger chemicals to release neurotransmitters that communicate messages to the body (2011, p. 85-86). The brain is a vital organ that determines our ability to function properly. There are many different areas or lobes in the brain that correspond to the different functions that the body can perform.…
There are nerve cells running through the entire length of the body and this includes the organs. Have you ever thought why you are not experiencing any forms of pain, when you are stretching? The internal organs, primarily the lungs are rubbing against the chest cavity, and yet you are never experiencing any form of pain. The same can be applied when you are breathing heavily. We are not experiencing pain because almost all the major organs and cavities within the body are lined by mesothelium.…
In anatomy and physiology class we learn about the human body and its composition. To see and learn about the body structure and its organ system we dissected a pig. The systems that we have in our body are the digestive system, the cardiovascular system, the integumentary system, the skeletal system, the muscular system, the lymphatic system, the…
Although a process such as answering your phone may sound simple, there are many activities and processes that are occurring in your body to make answering your phone possible. One primary human body system that collects stimulus and impulses which channel them throughout the body to allow a response to occur is called the nervous system. The nervous system has many unique cells, about 100 billion, called…
The brain is the most important body organ in your body nothing can function without your brain. The brain contains the way it moves, feels, and its senses of emotions, including the lungs, heart, and stomach. which is the part to the central nervous system. There are three main structures of the brain, the forebrain, midbrain, and hindbrain. Forbrain their are two different types of forebrain which is (diencephalon and telencephalon).…
The central nervous system deals with the brain and spinal cord. It also controls everything we need to survive on a daily basis. The central nervous system consists of our heart rates, our body temperatures, and breathing, just to name a few and all of these core things that we need to survive and are involuntary. We do not think of having to breathe or make our heart beat. The peripheral nervous system, also known as PNS, is what is consisted of everything outside of the brain and spinal cord.…
1. In your own words, how would you describe a stressor? A stressor is a situation or occurrence that causes stress. 2.…
The nervous system is composed of two main parts which are the central nervous system and the peripheral nervous system. The central nervous system includes the brain and nerve cords like the spinal cord while the peripheral nervous system includes the motor nerves and sensory nerves. There are two main types of support cells in the nervous system which are glial cells and neurons. The neurons' function in the system is to receive and send electrical signals. The glial cells provide insulation and regulation to neurons.…
