Termini in questo insieme (33)

  • Autocrine Signaling

    A process where the cell secretes chemical messengers that binds to a receptor on its own surface. triggering a response in the cell.

    • Quick Memory Trick: "Auto" = self. The cell is talking to itself.

  • Neuroendocrine signaling

    A process where specialized nerve cells (neurons) translate brain electrical inputs into chemical messenger molecules (Hormones) directly into blood stream.

    • Quick Memory Trick: Neuro (brain/neurons) + Endocrine (hormones in the blood).

  • Local Regulators

    Secreted molecules that act on the cell that secreted it

  • Prostaglandins

    Local chemical signals made from fatty acids that act on a nearby cell and help regulate things like information, pain, blood flow/

    • Quick Memory Trick: Think Prostaglandins = Pain, Puffiness (inflammation), and Pumping (blood flow).

  • Nitric Oxide

    A gas produced by many cells that function as local regulators and neurotransmitters.

  • Neurotransmitters

    Chemical messenger released by a neurons across a synapse and binds to receptors on another cells.

  • Neurohormones

    Molecules secreted by a neuron

  • Signal Transduction

    Cell takes an external message and translates it into sction, basically a chain reaction of molecular signals inside.

    • Quick Memory Trick: Think Transduction = Translation. It translates an outside signal (the stimulus) into an inside action (the cellular response).

  • Epinephrine

    Basically adrenaline.

  • Endocrine Glands

    Ductless organs that release hormones into the bloodstream

  • Oxtocin

    A natural hormone and a brain chemical messenger that is produced in the hypothalamus, and released into pituitary glands.

  • Pituitary gland

    A endrocrine gland thats is at the base of hypothalamus(below) which help regulate growth metabolism, reproduction, stress,

  • Posterior Pituitary.

    The back lobe of the pituitary where it makes and releases hormones made by hypothalums.

  • Anterior Pituitary

    Portion of the pititary which is disconnected from the hypothalmus made from non-tissue and consists of endrocrine cells which secreate non-tropic and tropic hormones.

  • Thyroid Hormones

    Control your bodys metabolism, which means how much your body turns food into energy there are two types of throid hormones t3 and t4.

  • Thyroid Gland -

    a small butterfly shaped endocrine organ located at the lower front side of neck. Secretes t3 and t4 also calcitonin.

  • Growth Hormones

    A hormone that is produce and secreted by the anterior pituitary , and has both tropic and non tropic affects on tissues.

  • parathyroid glands

    one of four endocrine glands that is fixed on the surface of the thyroid gland , that secretes parathyroid hormones.

  • Parathyroid Hormones

    A hormone that is secreted by the parathyroid glands to increase blood calcium

  • Calcitonin

    A hormone that is secreted by the thyroid gland to lower blood calcium levels.

  • Adrenal Glands

    two small triangle shaped organs located on top of the each kidney to produce essential hormones to control blood pressure, stress, metabolism

  • Norepinephrine

    Also called nonadrelinine , which is neurotransmitters and hormones that increase alertness and raises heart rate, blood presuure durring stress.

  • Glucocorticoids

    A steroid hormone that is secreated by the adrenal cortex and influences glucose metabolism and immune function.

  • Mineralocorticoids

    A steroid hormone that is secreated by the adrenal cortex to help regulate salt and water homeostasis .

  • s(hormone)

    Androgens

    Any hormone such as testosterone, that stimulates the male reproductive system.

    Quick Memory Trick: "Andro" literally means "man" in Greek (think of the word androgynous or android). It is the umbrella term for male hormones.

  • Testosterone

    A steroid hormone required for the devopment of the male reproductive system

  • Estrogens

    Any Steroid hormone, such as estradiol that stimulates the development of the female reproductive system.

  • Estradiol

    A specific steroid hormone that stimulates the development and maintenance of the female reproductive system.

  • Progesterone

    A steroid hormone that contributes to the menstrual cycle and prepares the uterus for pregnancy.

    Quick Memory Trick: Think Pro-Gestation. It is strictly a "Pro" (for) "Gestation" (pregnancy) hormone, getting the uterus ready to host a baby.

  • Melatonin

    Secreted by the pineal gland that is included in the regulation of the biological rhythms and sleep.

  • Pineal gland

    A small gland on the dorsal surface of the the vertebrate forebrain that secretes the hormone melatonin.

  • Prolactin

    Hormone produced and secreted by the anterior pituitary with a great diversity of affect in different species. In mammal it stimulates milk production by mammary gland.

  • Melanin stimulating Hormone ( MSH)

    A peptide hormone produced primarily by the intermediate lobe of the pituitary gland. It stimulates melanocytes in the skin and hair to produce and release melanin, providing UV protection and regulating pigmentation.
