NEUROLOGICAL SYSTEM DIVISIONS OF THE NERVOUS SYSTEM: 1. Central Nervous System (CNS)=Brain & Spinal Cord 2. Peripheral Nervous System (PNS) a. Autonomic Nervous System=System Homeostasis b. Sympathetic Nervous System=Fight or Flight c. Parasympathetic Nervous System=Rest & Digest d. Enteric Nervous System=GI system NEURONS 1. 3 parts of a nerve cell a. Dendrites b. Cell Body c. Axon 2. Types of nerves: a. Afferent Neurons=sensory‚ conduct impulses TO the brain b. Efferent Neurons=motor

cavities. Body membranes are made up of epithelial and connective tissue layer. Mucous membrane cover openings that are exposed to the outside world. For example‚ mucous membrane is present in the nose‚ respiratory tract‚ male and female reproductive systems‚ stomach and intestines. Epithelium of mucous membrane is attached to lamina propria‚ a loose connective tissue layer that stabilizes the epithelium in place. Goblet cells in the epithelium make mucus which is a liquid that protects the mucous membrane

Meningeal Branch: Tiny‚ reenters vertebral canal‚ innervates meninges and blood vessels (2) Distinguish among exteroceptors‚ interoceptors and proprioceptors. Exteroceptors: Respond to stimuli arising outside body Receptors in the skin for touch‚ pressure‚ pain‚ and temperature Most special sense organs (vision‚ hearing‚ equilibrium‚ taste‚ smell) Interoceptors:

The nervous system is the most important system in the body. It transmits impulses to and from the brain. Disruption of the nerve cells and fibers that transmit the messages severely impairs the body’s ability to carry out complex function. Once a disruption occurs‚ one may never recover and neurological function will steadily degrade. Multiple Sclerosis is a disease that disrupts this network. Multiple Sclerosis (MS) is the most common disabling neurological disease in young adults between 20 and

The Hypothalamic-Pituitary-Adrenal System (HPA) 2. The Sympathetic-Adrenal-Medullary Pathway (SAM) AO1: The Hypothalamic-Pituitary-Adrenal System (HPA) Some stressful experiences last for a long time‚ such as worrying about exams for months

1. A researcher strongly believes that physicians tend to show female nurses less attention and respect than they show male nurses. she sets up an experimental study involving observations of health clinics in different conditions. In explaining the study to the physicians and nurses who will participate‚ what steps should the researcher take to eliminate experimental bias based on both experimenter expectations and participant expectations.? The first step should be to consider that using an experiment

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
