Structures of the Nervous System This activity will increase your understanding of the different structures of the nervous system and brain. During the Web activity‚ you will view a variety of structures of the brain and nervous system and label each with the appropriate term. You will use this document to write a description for the terms you used in the activity. As you conduct the Structures of the Nervous System activity‚ follow along with this Word document and fill in the descriptions of

First of all‚ what is BRAIN? Brain is an organ in our body that controls functions‚ movements‚ sensations and thoughts and ability to reason out. If we don’t have we cannot move‚ think‚ and have a normal life in short we die. Our heart pump approximately 20% of blood in our brain. The brain needs constant blood flow in order to keep up with the heavy metabolic demands of the neurons. The brain is the main control center for all individual activities. It controls our muscular activities or movements

14: The Autonomic Nervous System Objectives Introduction 1. Define autonomic nervous system and explain its relationship to the peripheral nervous system. 2. Compare the somatic and autonomic nervous systems relative to effectors‚ efferent pathways‚ and neurotransmitters released. 3. Compare and contrast the functions of the parasympathetic and sympathetic divisions. ANS Anatomy 4. For the parasympathetic and sympathetic divisions‚ describe the site of CNS origin‚ locations of ganglia

Anatomy of Peripheral Nerves Peripheral nerves consist of fascicles that contain myelinated and unmyelinated axons. Endoneurium is the small amount of matrix that is present between individual axons. The perineurium is a sheath of special‚ fiber-like cells that ties the axons of each fascicle together. 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

The divisions of the nervous system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The CNS is made of two parts the brain and the spinal cord. The PNS is made up the Somatic nervous system and the automatic system. The somatic nervous contains the peripheral nerve fibers that deliver sensory information to the CNS and motor nerve fibers that go to the skeletal muscle. The central nervous system sends messages from the brain to the rest of the body. (Divisions of The

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 called soma contains the nucleus‚ which itself has the genetic

Psychology The Nervous System The nervous system is divided into two main areas‚ the peripheral nervous system and the central nervous system. The central nervous system controls the brain and spinal cord. The average human brain weighs approximately 3 pounds and contains approximately 100 billion neurons‚ as well as trillions of “support cells” called glia. The spinal cord weights approximately 35-40 grams and is around 43 cm long in adult woman and 45 cm long in adult men. The frontal

Lab IX: Nervous System Histology and Spinal Cord Part II: Neurons and nerve struture 1.) There are three types of neurons. The first is the multipolar‚ which is the most common‚ and they are found as motor neurons and interneurons throughout the central nervous system. The second type of neuron is the unipolar neuron‚ which are also called psuedounipolar neurons. They are found as spinal and cranial sensory neurons. The last neuron is the bipolar neuron. They are only found in olfactory‚ visual
