Describe the path of a nerve impulse in a neuron starting with the dendrite

The electrical charge travel through the neural cell membrane and thus generates a nerve impulse. The nerve impulse travels through membrane of neural cell by the movement of ions across the membrane. The nerve impulse signal will travel through the neuron and reaches at the end of a neuron that is axon terminal. The end (axon) of a neuron connects with the  dendrites of second neuron with the help of molecules known as neurotransmitters. This connection between two neurons that allows the nerve impulse to travel is called synapse.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
