1.) Name and describe the function of each part of a neuron. What is a neuron? The neurons are the basic elements of our nervous system. You can call them specialized cells in which includes the units of info-development in our brain‚ are very responsible for the perception and the transportation of information. Each part of the neuron has a very important role providing information in the whole body. The most important parts of a neuron are: a cell body‚ dendrites‚ and an axon. • Cell Body‚ also

The central nervous system (CNS) is that portion of the vertebrae nervous system that is composed of the brain and spinal cord. Together with the peripheral nervous system (PNS)‚ the other major portion of the nervous system‚ the CNS coordinates the body’s interaction with the environment. The CNS is contained within the dorsal cavity‚ with the brain in the cranial subcavity (the skull)‚ and the spinal cord in the spinal cavity (within the vertebral column). Then human nervous system is the most

The Autonomic Nervous System Sympathetic (Thoraco-lumbar) division Parasympathetic (Cranial-sacral) division Somatic Motor vs Visceral Motor ■ ■ ■ ■ Somatic motor is directed from cortical levels to skeletal muscles and is voluntary. Visceral motor is directed from hypothalamus and midbrain and is involuntary‚ but has input from cortex and thalamus. Somatic lower motor neuron is in ventral horn of gray matter and neurotransmitter at skeletal muscle is Ach. Visceral motor comes from cranial nerves

The nervous system is one of the smallest yet one of the‚ if not the most‚ complex systems in the human body. It can be broken down into two main subdivisions‚ the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system contains about 85 billion neurons and includes the spinal cord and brain. It is considered the control center of the body and processes all types of incoming sensory information. The peripheral nervous system is composed of all the other tissue

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
