Introduction:
Hormones are chemical messengers secreted by the endocrine glands or neurosecretory cells into the extracellular fluids. The secreted hormones reach the target cells through the bloodstream, and they stimulate response of other tissues or cells. Hormones bind only to specific cells based on their corresponding receptors present on cells. They act through chemical signals. They regulate growth, development, blood pressure,

- ADH and oxytocin are hypothalamic hormones secreted from the pituitarys _____________ lobe. a. anterior b. posterior c. primary d. secondaryarrow_forwardDescribe how hormone receptors can play a role in affecting the size of the responses of tissues to hormones.arrow_forwardSelect the best answer or answers from the choices given: Some hormones act by (a) increasing the synthesis of enzymes, (b) converting an inactive enzyme into an active enzyme, (c) affecting only specific target organs, (d) all of these.arrow_forward
- Which of the following is not a hormone? a. prolactin b. thymosin c. iodine d. natriuretic peptide e. insulin-like growth factorarrow_forwardEndocrine hormones are molecules released by cells that are parts of the________. These cells are embedded in capillary beds, so the hormones enter the bloodstream and move throughout the body. Only specific cells of the body, called______ , can respond to any given hormone, because only these cells bear proteins, called________ ,that can bind the hormone.arrow_forwardNeuroendocrine glands are glands that are made up of both nervous tissue and endocrine tissue. This means that they can be directly stimulated by the nervous system to produce or release hormones. The pituitary gland and parathyroid gland are examples.Describe a situation/example for each (pituitary gland and parathyroid gland) that demonstrates the function mentioned above. Be specific.arrow_forward
