Questions Accurately Answered.
Long distance chemical signals that are secreted by the cells to the extracellular fluid and
regulate the metabolic functions of other cells. correct answers Hormone
Cells that have specific membrane or intracellular receptors to which hormones can bind. correct
answers Target Cell
Most hormone synthesis and release is regulated through correct answers Negative Feedback
Mechanisms
Hormones that stimulate other endocrine glands to secrete their products correct answers Tropin
(all amino acid-based hormones except thyroid hormone) exert their effects through an
intracellular second messenger that is activated when the hormone binds to a plasma membrane
receptor, activating G-proteins within the cell, which then alter enzyme activity correct answers
Water Soluble hormones
(steroid and thyroid hormone) diffuse into the cell, where they bind to intracellular receptors,
migrate to the nucleus, and activate specific target sequences of DNA correct answers Lipid
Soluble hormones
Include estrogen, testosterone, glucocorticoids (cortisol), mineralocorticoids (aldosterone), and
gonadocoritcoids (adrenocortical androgens) correct answers Steroid hormones
Humoral, Neural, or Hormonal correct answers Endocrine gland stimuli may be
Hormone release caused by altered levels of certain critical ions or nutrients correct answers
Humoral
,Hormone release caused by neural input correct answers Neural
Hormone release caused by another hormone (a tropic hormone) correct answers Hormonal
Decreased insulin secretion correct answers Diabetes Mellitus; Type 1
Decreased cellular response to insulin
Symptoms: Polyphagia, Polyuria, Polydipsia, metabolic acidosis, glycosuria correct answers
Diabetes Mellitus; Type 2
Decreased secretion of ADH
Symptoms: Copious amounts of dilute urine produced correct answers Diabetes Insipidus
Decreased secretion of GH in childhood correct answers Dwarfism
Hyper-secretion of GH in childhood correct answers Gigantism
basophils (contain histamine granules),
eosinophils,
neutrophils (most abundant) correct answers Granulocytes
monocytes/macrophages, lymphocytes correct answers Agranulocytes
thrombocytes; fragments of megakaryocytic, function in blood clotting correct answers Platelets
, Consists of 4 polypeptide chains (2 alpha and 2 beta), each with an iron-containing heme group.
An oxygen molecule binds to the iron atom of each heme group. correct answers Structural
components of Hemoglobin
7.35-7.45 (7.4) correct answers Normal pH of blood is
Main contributor to maintaining colloid osmotic pressure of blood correct answers Blood
proteins: Albumin
(gamma globulins, antibodies); specific immunity, bind to specific antigens correct answers
Blood proteins: Immunoglobulins
Complement proteins correct answers Blood protein
Activated by platelet degranulation or tissue factor released by injured cells.
The result is conversion of prothrombin to the active enzyme thrombin, which converts soluble
fibrinogen to fibrin, which along with platelets and trapped RBCs for a plug (clot).
They need calcium as part of the activation process.
Several clotting factors require vitamin K for synthesis. correct answers Clotting factors
Activated by platelet degranulation or tissue factor released by injured cells.
