Physioex Exercise 3: Neurophysiology Of Nerve Impulses Compete Tests The two types of cells in the nervous system are neurons, neuroglia neuroglia is also known as _____ cells glial sensory neurons in the nose generate an electrical signal called receptor potential travels along the membrane of the sensory neuron's axon to the brain action potential the action potential releases chemical neurotransmitters chemical neurotransmitters bind to receptor proteins on the membrane of brain ____...

Neurophysiology of Nerve Impulses. Physioex 3 qestions with complete solutions 2024

Neurophysiology of Nerve Impulses. Physioex 3 correctly answered 20231. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. - correct answer Increasing the extracellular K+ reduces the steepness of the concentration gradient and so less K+ diffuses out of the neuron. 2. Explain why increasing the extracellular K+ causes the membrane potential to change to a less negative value. - correct answer The membrane potential became...

Nucleus - Control center of the cell. Contains DNA in the form of genes. Rough Endoplasmic Reticulum - System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. functions in transport of substances such as proteins within the cytoplasm Smooth Endoplasmic Reticulum - An endomembrane system where lipids are synthesized, calcium levels are regulated, and toxic substances are broken down. Mitochondria - An organelle found in large numbers in most ...

Action potential - Ans - a neural impulse; a brief electrical charge that travels down an axon - the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell. Axons - Ans a part of a neuron that carries impulses away from the cell body Broca's area - Ans Controls language expression - an area of the frontal lobe, usually in the left hemisphere, that directs the muscle movements involved in speech. Cell body - Ans Larges...
