Review Sheet Exercise 3 Neurophysiology of Nerve Impulses Eliciting (Generating) a Nerve Impulse 1. Why don’t the terms depolarization and action potential mean the same thing? They require different things. Action potential requires depolarization and repolarization. Depolarization doesn’t require anything. 2. What was the threshold voltage in Activity 1? 3.0V 3. What was the effect of increasing the voltage? How does this change correlate to changes in the nerve? The action potential

Hormones and the Endocrine System 26.1 Chemical and electrical signals coordinate body functions The Endocrine System is a group of interacting glands and tissues throughout the animal body that produce and secrete chemical to initiate and maintain body functions and activities. Chemical Signals -Hormones - are released into the bloodstream by endocrine cells and carried to all locations in the body Consists of all hormone secreting cells Works with the nervous system in regulating body activities

Physiology Exercise 3 Activity 1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: By increasing the extrecellular K+ the net diffiusion of K+ out the neuron through the eak channels is reduced. This is caused by the flow of ions following the concentration gradient of traveling from an area of high concentration to areas of low concentration. The higher concentration gradient would result in a reduced diffusions

PhysioEx 9.0 Exercise 3 Neurophysiology of Nerve Impulses A C T I V I T Y 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 potassium reduces the concentration gradient‚ and less potassium diffuses out of the neuron and into the cell. 2. Explain why increasing extracellular K_ causes the membrane potential to change to a less negative value.

The Endocrine System System Although we rarely think about them‚ the glands of the endocrine system and the hormones they release influence almost every cell‚ organ‚ and function of our bodies. The endocrine system is instrumental in regulating mood‚ growth and development‚ tissue function‚ and metabolism‚ as well as sexual function and reproductive processes. In general‚ the endocrine system is in charge of body processes that happen slowly‚ such as cell growth. Faster processes like breathing

Human Endocrine System A system of glands and cells that make hormones that are released directly into the blood and travel to tissues and organs all over the body. The endocrine system controls growth‚ sexual development‚ sleep‚ hunger‚ and the way the body uses food. [pic] The human endocrine system modulates several processes of the body by the function of hormones. The endocrine system secretes hormones that control how bodily functions work. Thus‚ the human endocrine system watches

The equine endocrine system is a group of organs that release hormones in the horses body to regulate things like growth‚ metabolism‚ and reproduction. Hormones production is directed by brain signals caused by outside stimuli and it maintained through negative and positive feedback loops. One of the main organs in the endocrine system is the pituitary gland located on the floor of the skull. The hormones produced by the pituitary have a variety of functions from metabolism to reproduction. The most
