|
|
|
stimulus and receptor are part of the afferent pathway of the endocrine system
|
|
|
insulin, released by the pancreas in response to increased blood glucose levels, is an example of an efferent signal
|
|
|
the brain is the control center
|
|
|
the blood vessels carrying insulin through the body is an example of an effector

Detailed explanation-1: -A simple endocrine reflex pathway is controlled by just one hormone, while a complex one has multiple hormones that work together to control it. The first step in the pathway is the release of a hormone from an organ or tissue, which travels through the bloodstream and signals cells in other organs or tissues.
Detailed explanation-2: -The endocrine system regulates the metabolic activities of the body like body growth, sexual development & other biological processes. The endocrine gland signalling is slow but its effects are prolonged. Some of the major endocrine glands are the Pituitary, Pineal, Thyroid, Thymus, Gonads, etc.
Detailed explanation-3: -Glucose, the regulated variable, is the principal source of energy for the organism in general, and particularly for the brain. During fasting, the liver (the main effector) breaks down stored glycogen, and glucose is secreted into the bloodstream.
Detailed explanation-4: -Q. Which of the following is an example of the endocrine system directly interacting with the nervous system? The vertebrae protect the spinal cord from injury. Hormones provide feedback that affects neural processing.
