|
CNS |
Includes the spinal cord and the brain. |
|
|
PNS |
The nerves that ascend from the spinal cord (the nerves that are not part of the spinal cord). |
|
|
Afferent |
Collect information from stimulus and deliver it to the brain (sensory neurons). |
|
|
Interneurons |
are neither Sensory or motor neurons, but is a neuron that forms a connection between two neurons, and are long (mostly between Afferent and Efferent neurons, entirely in the CNS). |
|
|
Efferent Neruons |
Deliver information from the brain (motor neurons) so you use them to react to your environment. |
|
|
Neurons |
Cells that collect information and send signals through action potentials. |
|
|
Glial Cells |
Neuronal support cells, maintain homeostasis. |
|
|
Schwann cells |
Is a glial cell, in the PNS and produce myelin sheath. |
|
|
Oligodendrocytes |
Is a glial cell, in the CNS and produce myelin sheath. |
|
|
Astrocytes |
Help form the blood brain barrier secrete nerotrophic factors take up K+, water and neurotransmitters provide substrates for ATP production be a source for neuronal stem cells |
|
|
Ependymal cells |
Produce CSF (cerebrospinal fluid) and create barriers between CNS structures in an epithelium like fashion. |
|
|
Prostaglandin |
A group of active lipid compounds, they facilitate slow muscle movement in males and females. |
|
|
Bulbourethral gland |
Lubricates the distal urethra, clears away urine, and recoagulate the sperm. |
|
|
Functions of the male reproductive anatomy, physiology and or behavior |
Delivery of male gametes to females gametes production of sperm (spermatogenesis, protection and sotrage) produce reproductive hormones - androgens, steroidgenesis - (productin of primary and secondary characteristics Locate and attract females |
|
|
Functions of the female reproductive anatomy, physiology and or behavior |
-Oogenesis - production of eggs -Nourishment and production of gamete and production of offspring -steroidogenesis and other hormones (production of primary and secondary sexual characteristics). -Lactation in mammals -recieve sperm -locate and attract males -child birth |
|
|
Follicle-stimulating hormone (FSH) |
It is secreted from the anterior petuitary For the dudes stimulates the leydig cells to produce androgen binding proteins to start spermatogenesis. For the ladies, stimulates ovaries to produce eggs, and (along with LH) triggers ovulation. |
|
|
Lutenizing hormone |
It stimulates the production of testosterone and it helps to trigger ovulation. |
|
|
Seminal vesicle |
lubrication, dillution, fructose so the sperm can move (provides energy), and prostoglandins for smooth muscle contraction. |
|
|
prostate |
secretes alkaline component to neutralize acidic environment of female reproductive tract. |
|
|
bulbourethral glad |
provides lubrication, clears away urine from urethra, and acts to recoagulate sperm. |
|
|
Oviparous |
lay eggs, fish. |
|
|
Ovovivparous |
young develop in egg in mom and then born live. like snakes. |
|
|
Viviparous |
young deveop in mom in uterus not in an egg and then born live. |
|
|
Equilibrium potential |
potential for a SINGLE ion type where the electrical gradient exactly counterbalances there concentration gradient. Measured by finding the potential inside the cell and outside the cell using either a coltmeter, nernst for single ions, goldman-hodgkin-katz equation. |
|
|
Nernst |
for 36 degrees C, (61/z)log([out]/[in]). under 18 degrees C, (58/z)log([out]/[in]). |
|
|
GHK |
used to find the net movement in an environment with many juxtaposed to nernst equation that deals with only one ion, is it better to estimate the Vm as it considers the permiability of ions. |
|
|
Sertoli cell |
nurse cell, nourishes the spermies. |
|
|
Leydig cells |
adgecent to seminiferous tubules and produce testosterone in presence of LH |
