times required. The system within the body which assists to control and coordinate the functioning of all the systems is called the nervous system. The nervous system works alongside the endocrine system allowing communication and coordination between the many organs and systems within the human body. This allows them to function correctly‚ and have the ability to respond to stimuli when needed. The nervous system has two main systems within itself. These are the central nervous system known as CNS‚ and

tissue is found in ligaments‚ tendons‚ cartilage‚ and bone. Nervous tissue forms the nervous system‚ which is responsible for coordinating the activities and movements of your body through its network of nerves. Parts of the nervous system include the brain‚ spinal cord‚ and nerves that branch off of those two key parts. Nervous tissue consists of two kinds of nerve cells: Neurons are the basic structural unit of the nervous system. Each cell consists of the cell body‚ dendrites‚ and axon. Neuroglia

The Biology of Mind Neuron Communication Neuron is a nerve cell‚ basic building block our nerve system Neurons consists in: Dendrites : neurons bushy branches and it listens Axons: Tube that passes the messages and it speaks – transmit Action potential : is a neural impulse‚ brief electrical charge that travels down an axon. Threshold: is the level of stimulation required to trigger a neural impulse Myelin Sheath covers an axon and some neurons Synapse : is the junction

The Nervous System (pp. 54-57) 4. Identify the major divisions of the nervous system and describe their functions‚ noting the three types of neurons that transmit information through the system. 5. Contrast the simplicity of the neural pathways involved in reflexes with the complexity of neural networks. The Brain (pp. 58-80) 6. Identify and describe several techniques for studying the brain. 7. Describe the functions of the brainstem‚ thalamus‚ cerebellum‚ and limbic system.

Neurogenic Shock Neurogenic shock is a type of shock that is caused by a spinal cord injury that affects important nerves in the nervous system. Injury to the nervous system causes the walls of blood vessels to relax‚ which increases the blood pressure. Neurogenic shock mainly affects the spinal cord. The spinal cord consists of nerves that carry incoming and outgoing messages between the brain and the rest of the body. Neurogenic shock occurs when a spinal cord injury happens‚ particularly involving

they function. Module eight contains information about the nervous system and the endocrine system‚ and it also explains how the body communicates from within. Module nine is the last module and contains information on the brain. The different parts and functions of the brain are also found in module nine. Module 7 Neurons are the most basic elements of the nervous system. They are tasked with relaying messages from the central nervous system. Neurons are a web that connect from your brain and spinal

Lab Report: Exercise 10: Organization of Nervous Tissue Purpose: What is the purpose of this exercise? Are there any safety concerns associated with this exercise? If so‚ list what they are and what precautions should be taken. To understand the structure and function of multipolar neuron‚unipolar and bipolar neurons. Also to identify the structures of a nerve. There are no safety concerns for this lab. Step 1: Relates to Lab Exercise 10/Activity 1‚ 3‚ and 4. Assignment 1: Write a brief description

Biological psychology hypothesises that the nervous system has the ability to influence the way we see the world around us. So much hinges on the existence of these cells that even different schools can agree upon their existence. A nerve cell‚ also known as a neuron‚ is defined as “Any of the impulse

A Better Understanding: Neurochemistry of Addiction To better understand the fundamentals of neurochemistry‚ a good start is at the brain. The brain makes up the central nervous system and is connected to the whole nervous system that runs through the whole body. The central nervous system receives sensory information and controls the body’s response. For example‚ a pot on a stove would be extremely hot on the hands when the stove is on and would damage the skin. This sensory information is sent
