Some examples from this set of practice questions
1.
What is a Hormone?
Answer: A molecule that is secreted into the extracellular fluid, it circulates in the blood or hemolymph, and it communicates regulatory messages throughout the body. The circulatory system allows a hormone to reach call cells of the body, but only its target cells have the receptors that enable a response.
2.
Hemolymph
Answer: A fluid, analogous to the blood in vertebrates.
3.
What is the function of the endocrine system?
Answer: The function is chemical signaling by hormones. Hormones secreted by endocrine cells regulate reproduction, development, energy metabolism, growth and behavior.
4.
What is the nervous system?
Answer: A network of specialized cells (neurons) that transmit signals along dedicated pathways. These signals in turn regulate other cells, including neurons, muscle cells and endocrine cells.
5.
What is a neuron?
Answer: (nerve cell) An electrically excitable cell that processes and transmits information through electrical and chemical signals.
6.
What is a synapse?
Answer: In the nervous system, a synapse is a structure that permits a neuron (nerve cell) to pass an electrical or chemical signal to another neuron. (Pathway)
7.
Do the endocrine and nervous system overlap? Explain
Answer: Yes. Because signaling by neurons can regulate the release of hormones, the nervous and the endocrine system often overlap in function.
8.
How do hormones and other signaling molecules work?
Answer: Bind to target receptors, triggering specific response pathways
9.
Name 5 types of signaling.
Answer: 1 Endocrine signaling 2 Paracrine signaling 3 Autocrine signaling 4 Synaptic signaling 5 Neuroendocrine signaling
10.
How does endocrine signaling works?
Answer: hormones secreted into extracellular fluids by endocrine cells reach target cells via the bloodstream. (Any where in the body)
