How The Skin is Involved with the Nervous System The skin is the outside covering of the body tissue‚ which protects inner cells and organs from the outside environment. The skin is the largest organ of the body and its cells are continuously replaced as they are lost to normal wear and tear. The skin has between 12 to 20 square feet in area and accounts for 12% of body weight. It is composed of 3 layers the epidermis‚ the dermis‚ and the sub cutis. The thickness of

THE NERVOUS AND THE ENDOCRINE SYSTEM. Humans need both the Nervous and the Endocrine systems basically because they do different things in different ways. They both have a co-ordination role and send instructions to other parts of the body. The nervous system does this by way of neurotransmitters‚( chemical messengers)‚ which are able to get messages through at very high speeds‚ and the endocrine system by way of hormones‚( also chemical messengers)‚ which are released from glands and travel

The nervous system comprises the central nervous system which is made up of the brain and spinal cord‚ with the main functions being processing information and determining responses and the peripheral nervous systems which is made up of all sensory‚ motor and inter neurons within the body and these are located on peripheral nerves. All of them work together to collect sensory data and also control the actions of the body. Sensory neurons collect sensory information and convey it to the brain‚ and

Let’s explain the difference between classification‚ matching‚ sorting and seriation. When it comes to classification you have to involve matching and sorting. However‚ they all have their differences. Matching involves collecting materials that are alike. Which can include pictures‚ balls‚ scarfs

Assignment 3 Written Essay Questions 1. a) We are able to experience different types of sensations because our nervous system encodes messages. German physiologist Johannes Muller in his doctrine of specific nerve energies described a kind of code which is anatomical. In his doctrine‚ Muller explains that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways that lead to different areas of the brain. For example‚ when the ear

Epineurium is the connective tissue that surrounds the entire nerve trunk and gives off vascular connective tissue septa that traverse the nerve and separate fascicles from one another. | | Single myelinated axon | Normal nerve | Axons thicker than one micron in the CNS and peripheral nervous system (PNS) are myelinated. Myelin is a spiral sheet of cell membrane wrapped around the axon. In the CNS‚ myelin is produced by oligodendroglial cells and in the PNS by Schwann cells. Each

central computer that controls all the functions of your body‚ then the nervous system is like a network that relays messages back and forth from it to different parts of the body. It does this via the spinal cord‚ which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part. When a message comes into the brain from anywhere in the body‚ the brain tells the body how to react. For example‚ if you accidentally touch a hot stove‚ the nerves
