Answer:
The neuron will not fire an action potential.
Explanation:
The missing magnitudes of the synaptic potentials when they reach the postsynaptic cell's axon hillock are:
A. excitatory +7
B. excitatory +10
C. inhibitory -3
D. excitatory +2
E. inhibitory -4
To fire the action potential, the summation of excitatory postsynaptic potentials (EPSP) and inhibitory postsynaptic potentials (IPSP) must reach the action potential threshold, which in this case is 15mV more positive than the resting potential.
The EPSP are: +7 +10 +2= +19
The IPSP are: -3 - 4= -7
EPSP + IPSP=
+19 -7 = +12 mV
The neuron will not fire an action potential since the integration of EPSP and IPSP is below 15mv.
Answer:
<u>Luteinizing hormone </u>(LH) stimulates Leydig cells to secrete testosterone
<u>Follicle stimulating hormone (FSH)</u> stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis
Explanation:
Under the influence of gonadotropin-releasing hormone, the anterior pituitary releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In males, LH stimulates interstitial cells of testes (Leydig cell) to secrete the hormone testosterone. FSH acts indirectly to stimulate spermatogenesis by causing the release of androgen-binding protein (ABP) from the Sertoli cells. The function of ABP is to maintain the higher concentrations of testosterone to stimulate the final steps of spermatogenesis in the seminiferous tubules.
