Axons are long nerve processes which carry nerve impulses from the Soma to other neurons, they vary in length but can become almost as long as half of the human body.
The soma (body) of the neuron contains the nucleus which acts as the cell's control centre, these contain many small neurofibrils which project from the nucleus into the dendrites.
Dendrites are short, thick processes which branch out of the soma in a tree like manor. They conduct nerve impulses to the soma.
The three categories of neurons:
Afferent (Sensory) Neurons have the dendrites connected to receptors such as the eyes, ears etc. These receptors change the information they receive into electrical impulses that are transmitted to other neurons. In sensory neurons the axons are connected to other neurons.
Efferent (Motor) Neurons have the dendrites connected to other neurons, the axons are connected to effectors. Effectors are either glands or a muscle cell that is the receiving end of the nerve impulse. The nerve, when excited will cause the effector to react (move, contract, or secrete etc).
Internuncial Neurons have both the dendrites and the axons are connected to other neurons. They are sometimes referred to as connector neurons.
Internuncial neurons are found throughout the body, but especially in the spinal cord and brain.
Properties and characteristics of Neurons:
Normally the electrical impulses (messages) travel through a neuron in only one direction.
The axon may be surrounded by a 'coat' of lipids (fats) and proteins known as the myelin sheath which acts as an insulator.
Neurons are specialist cells that have lost the ability to reproduce themselves. Once the soma of a neuron has died the entire neuron dies, and can never be replaced.
Repair of damaged neurons only occurs in myelinated neurons.
white matter are coloured by myelin, consisting of many neurons supported by neuroglia.
grey matter is soma and dendrites or bundles of unmyelinated axons and neuralgia.
Answer:
Good Parenthood Is Needed for the Childrens Mental and Emotional health, or pshycal health aswell ( I think ) and for future sake aswell
Good Parenthood Is Needed for Children Cause The children here today is going To be the next Generation of Human kind Well All Of the kids Is Going To be The next Generation of Human kind Thats Why They Are need To Be Tought well In studies for Y'know Might even Make another Inventions like what we have today Gadgets, T. V's, Car's and Other stuff But Thats were Teachers Come in, And When In need Of Affection and Love thats were The Parents/Family Come in Thats why The Parents/Family must give a Good Parent hood On Children or even Teenagers of there Son/Daughters Cause if Not The children might think think Of Why The parent wont Show them Affection or stuff And They might think of Suicidal stuff Like Example; Abusive Family Or Strict family, That kind Of stuff Thats why Parents must Avoid Giving Children Negative Thoughts

I think it’s B. The climate changed, and crocodiles could not survive in this region,
it sounds right
hope this helped! :)
