Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 Neurophysiology of Nerve Impulses Activity 1: The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain

RESPIRATORY SYSTEM Respiratory System Organs and Its Functions Introduction to the respiratory system organs: The respiratory system is the system of the human body by which it produces energy needed for life processes. This energy is produced by the breaking down of glucose molecules in all living cells of the human body. Introduction to the respiratory system organs: In simple terms‚ Oxygen taken in to the body through air breathed in is transported to all parts of the body‚ and it

Review Questions 1. What is the nervous system? What does it two? What two parts make up this system?It coordinates the actions of the animal and sends messages from one part of the body to another. It is composed of the brain and the spinal cord. 2. What is the gastrointestinal system? What does it do? It digests ingested food and gets rid of any waste after the food is digested. 3. What is epilepsy? What are the two different types of epilepsy? A disease of reoccurring seizures. Symptomatic

Bit about the brain: Structurally‚ the neuron has 4 main components; dendrites‚ the soma or cell body‚ the axon‚ and terminal fibers.. Imagine a big tree suspended in mid-air. This tree has a dense network of roots which join on to a bulbous lower trunk. Above this fat lower trunk is a long thin upper trunk which ends with a wispy network of branches. In this pictured analogy of the neuron or nerve cell‚ the roots of the tree are the dendrites‚ the lower bulbous trunk is the soma‚ the long upper

Cell Structure Vocabulary Cell Membrane → the semipermeable membrane surrounding the cytoplasm of a cell. Cell Wall → a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants‚ fungi‚ and bacteria. In the algae and higher plants‚ it consists mainly of cellulose. Cellular Respiration → A series of metabolic processes that take place within a cell in which biochemical energy is harvested from organic substance (e.g. glucose) and stored as energy carriers
