How Does The Endocrine System Maintain Homeostasis
The endocrine system works with the nervous system to maintain homeostasis. The endocrine system secretes hormones in the human body, which are produced in endocrine glands and are released into the bloodstream to travel to the its specific target cell, tissue, or organ. Exocrine glands produce chemicals that are discharged into the surroundings. Hormones can either produce short-lived responses or long-term responses. An example of a short-lived response is when adrenaline (epinephrine)causes the flight-or-fight response. An example of a long-term response is the way ecdysone controls metamorphosis in insects.
Although the endocrine system does not depend on the nervous system to function, it does work with the nervous system to communicate …show more content…
They receive signals from other neurons or stimuli and process them. The incoming signal can be excitatory, meaning that it will generate an electrical impulse, or inhibitory, meaning that it will prevent the neuron from firing an electrical impulse. A neuron receives thousands of input signals from its dendrites, but whether the neuron is excited enough to the point it will generate an electrical impulse depends on the sum of the inhibitory and excitatory signals. The resting potential of a neuron is -70 MV, and the threshold to activate an electrical impulse (action potential) is – 55 …show more content…
Messages are sent to other neurons or muscles or glands from the axon and the axon terminal. Axons must be linked to one another for a signal to pass. The space between two neurons where neurotransmitters pass is called a synapse. When a nerve signal travels along the neuron to the synapse, neurotransmitters are released to carry that message to the next neuron. Once an action potential reaches the end of the neuron, an influx of calcium will release the neurotransmitters across the synapse. The neurotransmitters then match up with an ion-channel on the other neuron; the ion channel change its shape so that it can take the neurotransmitters into its neuron. These neurotransmitters either result in an action potential or inhibit an action potential.
Most neurons look very similar to one another, but the structure of an individual neuron depends on the functions/tasks it carries out. For example, a neuron in the brain might have more dendrites compared to those elsewhere in the body since the brain receives an enormous amount of synaptic
