Boo You Hor! (Mone)
This side of the pituitary gland releases tropic hormones
What is the anterior pituitary gland?
This hormone inhibits the release of FSH and lowers production of LH. This hormone is secreted by ______.
What is inhibin, Sertoli cells?
Once puberty starts, the primary oocyte resume meiosis I, and produces one viable egg that is a haploid, and a _____, which is incapable of fertilizing with sperm
What is the polar body?
Name of the structure that the hydrolytic enzymes of the _____ of the sperm break away at
What is the jelly coat, acrosome?
Name of the process when Na+ and K+ ions rush into the cell during an action potential
What is depolarization?
Name of the hormone that arises in the anterior pituitary gland whose target cell is an endocrine gland
What is a tropic hormone?
This structure, part of the male reproductive system, helps neutralize pH in the urethra
What is the bulbourethral gland?
Puberty is initiated by the release of this hormone that resumes meiosis I of the primary oocyte
What is FSH?
Fusion of the gametes leads to ____ channels open and causes _____ of the membrane, and this prevents _____ from fertilizing the same egg
What is ion; depolarization; sperm?
This mechanism helps maintain the resting membrane potential. The resting membrane potential usually ranges between _____ and _____ mV
What is the Na+-K+ pump (sodium-potassium pump); -60; -80?
Names of cells that arise in the hypothalamus that carry electrical signals and release hormones in the pituitary gland
What are neurosecretory cells?
This structure of sperm releases hydrolytic enzymes that digest the surrounding membranous layer of the egg
What is the acrosome?
This phase of the menstrual cycle produces estradiol only
What is the follicular phase?
This reaction involves the formation of a fertilization envelope
What is the cortical reaction?
These cells myelinate axons, _______ myelinate axons in the CNS, and ______ myelinate axons in the PNS. In myelinated axons, the signal travels ______ and between the _______, which are spaces between the myelinated areas of the axon. More myelinated axons results in the increase of this in the brain.
What are oligodendrocytes; Schwann cells; faster; Nodes of Ranvier; white matter?
List the events that need to occur in order for a hormone to reach its target cell via anterior pituitary gland
1) Stimulus needs to occur, this sends sensory neurons to the hypothalamus
2) Hypothalamus sends an inhibiting or releasing hormone to the anterior pituitary gland
3) Anterior pituitary gland sends a tropic hormone to an endocrine gland via the bloodstream
4) Endocrine gland releases its own hormone to reach the target cell
This spermatocyte is a result of meiosis I and becomes a haploid cell
What is a secondary spermatocyte?
Ovulation marks the end of the _____ phase and the beginning of the ____ phase
What is follicular; luteal?
The acrosomal reaction is a ____ block, and the cortical reaction is a _____ block
What is fast; slow?
This ion results in vesicles carrying neurotransmitters to the synaptic terminal of the neuron to bind to postsynaptic receptors that can trigger an EPSP or IPSP
What is Ca2+?
This disease is caused by the overproduction of thyroid hormone 3 (T3), which causes swelling of the thyroid gland
What is goiter?
These help protect and provide nutrients to the spermatids that undergo differentiation
What are Sertoli cells?
This cycle involves the endometrium being reabsorbed in absence of pregnancy. Can you find this cycle in humans?
What is the estrous cycle; No you cannot find this cycle in humans, because the human cycle is the menstrual cycle, and the estrous cycle involves animals (not humans) and certain primates?
The influx of Ca2+ in this reaction causes _____ to bind with the plasma membrane
What is the cortical reaction; cortical granules?
Opening of Na+ channels on the postsynaptic neuron results in this reaction
What is Excitatory Postsynaptic Potential (EPSP)?
