Linear acceleration Smell Taste Touch – Pressure Warmth Cold Pain Joint Movement and Position Muscle Length Muscle Tension All sensory information arrives at the central nervous system (CNS) in the form of action potentials and the stronger the stimulus‚ the higher the frequency of action potentials. For example‚ touch‚ pressure‚ pain‚ temperature and taste sensations arrive at the primary sensory cortex. The CNS interprets the nature of the sensory information entirely on the basis of the area of the

those it attaches to. Figure 1 shows a neuron‚ as indicated on the diagram; the dendrites are the receivers of information for that cell. The dendrites receive neurotransmitters from the synapses that connect to it and if enough are present‚ an action potential is caused which then travels down the axon to the terminal buttons also known as synapses. There are electrical and chemical synapses in the body although the vast majority are chemical. Electrical synapses are located in the retina and in

The Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic cardiac______ cells that initiate and distribute __impulses___ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of _heart depolarization___. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA Node __initiates the depolarizing

Explain what is meant by this phrase. This means that once the threshold is met‚ an action potential occurs. If the stimulus is too small an action potential does not occur. An action potential is usually initiated in an axon at or near what? The axon hillock‚ the initial segment‚ and the trigger zone. The adequate stimuli

face up or above. Prone means face down which is the opposite of supine. Proximal is next to or nearest the point of attachment. Distal is away from the point of attachment. For example my elbow is distal to my shoulder but proximal to my wrist. 2. A. The four types of organics are lipids‚ proteins‚ nucleic acids‚ and carbohydrates. This is because lipids help the body function by storing energy and nutrients‚ structural components of the cell membrane. Proteins help structure and function throughout

the Axon Myelin Sheath Axon A Briefly describe the role each of the following play in neural communication: 1. Dendrite: branching neuron structures that receive neural impulses from other neurons and convey impulses toward the cell body 2. Axon: long tube like structure that conveys impulses away from the neurons cell body toward other neurons/muscles or glands 3. Cell Body: part of the neuron containing the cell nucleus as well as other structures that help the neuron carry out
