    1. Differentiate between the somatic nervous system and the ANS. Somatic nervous system includes all of the neural pathways (neurons) that result in voluntary actions‚ basically anything that you can tell your brain to do like move your arm or stick out your tongue. The autonomic nervous system includes all of the neural pathways that result in involuntary actions‚ like your brain telling your eyes to blink or your intestines to contract‚ basically anything that you cannot control. 2.

    Autonomic nervous system The autonomic nervous system (ANS or visceral nervous system) is the part of the peripheral nervous system that acts as a control system functioning largely below the level of consciousness‚ and controls visceral functions. The ANS affects heart rate‚ digestion‚ respiration rate‚ salivation‚ perspiration‚ diameter of the pupils‚ micturition (urination)‚ and sexual arousal. Whereas most of its actions are involuntary‚ some‚ such as breathing‚ work in tandem with the conscious

    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

    the function of each part of a neuron. 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

    found in the central nervous system. Neurones are specialized to process information in the body. Neurones convey this information to one another through the stimulation of a detector neurone. This causing a brief change in the electrochemical gradient resulting in the neurone moving away from its resting potential. This is known as an action potential. Once initiated the action potential travels the length of the axon reaching the pre-synaptic terminal where the synaptic cleft separates the following

    Central Nervous System In the movie the Wizard of Oz‚ the Scarecrow desperately wanted a brain. He opened his lips‚ blinked his eyes‚ shook his head and said‚ “I haven’t got a brain‚ I’ve only got straw.” The reason for the emphasizing of his actions is because without a brain‚ those functions are not possible. The brain is the center of the entire body. It controls what we do and how we do it. The brain is the center of the central nervous system along with the spleen. It consists of 100

    Nervous System- Nerve Impulse When a stimulus is strong enough‚ a nerve impulse is generated in an "all or none" response which means that a stimulus strong enough to generate a nerve impulse has been given. The stimulus triggers chemical and electrical changes in the neuron. Before an impulse is received‚ a resting neuron is polarized with different charges on either side of the cell membrane. The exterior of the cell is positively charged with a larger number of sodium ions present compared
