Questions with 100% Correct Answers
Autocrine signaling Correct Answer cells respond to signaling substances that they
themselves secrete
Juxtacrine signaling Correct Answer requires direct contact between the neighboring
signaling and responding cell
Paracrine signaling Correct Answer Signal released from a cell has an effect on
neighboring cells.
Endocrine signaling Correct Answer secreted molecules diffuse into the bloodstream
and trigger responses in target cells anywhere in the body
T/F
Hormones can act in autocrine and paracrine signaling within endocrine signalling
Correct Answer True
Classic endocrine glands, and where do they release hormones Correct Answer
pituitary, thyroid, parathyroid, adrenals, gonads (ovaries and testes), pancreas
Release hormones into the extracellular space, eventually into the plasma
Classic endocrine gland are ductless, true or false Correct Answer True
What bridges the CNS and the endocrine system evolutionarily Correct Answer The
hypothalamus
Neurohormone Correct Answer A molecule that is secreted by a neuron, travels in body
fluids, and acts on specific target cells, changing their functioning.
Difference between a neurohormone and a neurotransmitter Correct Answer
Nervous system signaling Correct Answer Neurons transmit signals along dedicated
short routes connection specific locations in the body (fast)
Endocrine system signaling Correct Answer Signaling molecules released into blood
stream by hormone cells carries all over the body (slow)
What is a consequence of the endocrine system using longer tracts, and what does this
mean in terms of the receptors for these hormones? Correct Answer These hormones
are more dilute, as they absorb into peripheral tissues, and are in solution (blood)
