hormones - AnswerWhat are the chemical messengers secreted into the blood stream that act on cells
far away?
neurotransmitters - AnswerWhat are released by nerves to affect cells?
endocrine - AnswerWhat type of glands secrete chemicals (hormones) into the blood?
target organ cells - AnswerWhat are the cells that are acted on by hormones called?
hormones - AnswerWhat mechanism perform general functions of communication and control but a
slower, longer-lasting type of control than that provided by nerve impulses?
nonsteroid hormones (first messengers) - AnswerWhat mechanism binds to receptors on the target cell
membrane, triggering second messengers to affect the cell's activities?
steroid hormones - AnswerWhat mechanism binds to receptors within the target cell nucleus and
influence cell activity by acting on DNA?
hormone secretion - AnswerWhat, in the regulation of hormone secretion is controlled by homeostatic
feedback?
negative feedback - AnswerWhat, in the regulation of hormone secretion, are mechanisms that reverse
the direction of a change in a physiological system?
positive feedback (uncommon) - AnswerWhat, in the regulation of hormone secretion, are mechanisms
that amplify physiological changes?
, hypersecretion - AnswerWhat is secretion of an excess of hormone that is a mechanism of endocrine
disease?
hyposecretion - AnswerWhat is insufficient hormone secretion that is a mechanism of endocrine
disease?
autocrine - AnswerWhat intercellular chemical signal is secreted by cells in a local area and influences
the activity of the same cell type from which it was secreted (ex. prostaglandins)?
paracrine - AnswerWhat intercellular chemical signal is produced by a wide variety of tissues and
secreted into tissue spaces; usually has a localized effect on other tissues (ex. histamine,
prostaglandins)?
hormone - AnswerWhat intercellular chemical signal is secreted into the blood by specialized cells;
travels some distance to target tissues and influences specific activities (ex. thyroxine, insulin)?
neurohormone - AnswerWhat intercellular chemical signal is produced by neurons and functions like
hormones (ex. oxytocin, antidiuretic hormone)?
neurotransmitter (neurohumor) - AnswerWhat intercellular chemical signal is produced by neurons and
secreted into extracellular spaces by presynaptic nerve terminals' travels short distances and influences
post synaptic cells (ex. acetylcholine, epinephrine)?
pheromone - AnswerWhat intercellular chemical signal is secreted into the environment; modifies
physiology and behavior of other individuals (ex. sex pheromones released in the urine of many
animals)?
hypothalamus - AnswerWhat part of the brain governs the pituitary gland which then sends signals to
endocrine glands?
atrial depolarization - AnswerWhat does the P wave of the EKG represent?
5 liters - AnswerWhat is the average circulating blood volume for an adult human?
