from all parts of the body. Neuron: the basic cell that makes up the nervous system and that receives and sends messages within that system. Dendrites: branchlike structures that receive messages from other neurons. Soma: the cell body of the neuron responsible for maintaining the life of the cell. Axon: tubelike structure that carries the neural message. Glial cells grey fatty cells that provide support for the neurons to grow on and around‚ deliver nutrients to neurons‚ produce myelin to coat axons

Exp #2: Organization of Nervous Tissue Exercise 1: Multipolar Neurons Paste an image found on LabPaq site or Google images of a spinal cord smear and label its basic parts using basic labeling boxes provided. Identify the cell body‚ the nucleus‚ the large nucleolus‚ and granular Nissl bodies on the slide. Try to find the axon and differentiate it from the dendrites if possible. Hint: after pasting image‚ right click on it and select “order”‚ “send to back”. cell body nucleus large

below‚ complete all three. Write a 350- to 700-word response to the following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior. There are 2 neurons afferent neurons these carry messages to the central nervous system. Efferent neurons carry messages from the central nervous system. Neurons communicate through voltage changes. This can sometimes lead to quick action reaction sequence of voltage alterations.

Neurons‚ the Basic Elements of Behavior PSY 101 16 January 2011 One of the most basic yet complex systems in the universe is the biological organism‚ with even the simplest person being considered the most intricate and advanced biological entity alive. Each person’s actions are controlled by the brain‚ which when broken down to the simplest explanation is essentially the most advanced computer in the world and just like a standard home computer the brain is made up of several pieces to function

Neurons: The Basic Elements of Behavior Neurons‚ or otherwise called nerve cells‚ are the basic elements of our nervous systems. We have as many as one trillion nerve cells throughout our bodies. These cells are responsible for controlling our behavior. So what is a neuron? “A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways‚ but there is one key difference between neurons and other cells

Polarization of the neuron’s membrane: cell membrane is surrounded by neurons as other cell has a membrane. If a nerve cell is not stimulated‚ the membrane is known to be polarized. For a neuron to be polarized‚ it is by maintaining excess of sodium ions on the outside of the cell and excess potassium ions on the inner part of the cell. A volume of sodium ions and potassium ions usually leaks through its channel but the sodium ions and potassium ions pumps on the membrane that restores the (k+) back
