What changes occur in the brain during the teenage years?
teenagers think about the offspring with girls
Most neurons lack centrioles This observation explains?
Neurons lose their centrioles during differentiation, and they become incapable of undergoing cell division.
What are the differences between long and short reflexes?
I believe a short reflex is when one is partially aroused, as during a bumpy car ride or Kate Winslet's nude scene in Titanic. A long reflex is when the member becomes fully hugified, as during any Paul Walker movie.
An embryo during the late stages of development-?
An embryo during the late stages of development is known as a fetus.
Is the skeleton cartilaginous or bony during fetal development?
cartilaginous
What is a innate reflex?
Innate reflexes are reflexes that result from the connections of neurons during their development.
Are there bipolar cells in the ciliary ganglion?
Bipolar neurons in the ciliary ganglion only exist during embryonic development and in vitro. Adult in vivo choroid and ciliary neurons in the ciliary ganglion are all unipolar.
What is transient exburerance?
Transient exuberance is a temporary increase in the number of synaptic connections between neurons in the brain, often observed during early brain development. This phenomenon is crucial for the formation of neural circuits and learning.

How does the four major elements of a simple nervous pathway function during pain withdrawal reflex?
During a pain withdrawal reflex impulses are sent through different nerves and to the spinal cord. This reflex does not make it to the brain but only to the spinal cord. We call this involuntary action because we dont control reflexes. The sensory neurons are the first to recieve the impulse, then they travel to the interneurons, or associative neurons, and then they go to the motor neurons which carries the impulse to the central nervous system. Then the effector is the response, so in this case your musscle will contract.
What happens during infancy?
during infancy, a child relates to the world through reflexes as means of their survival.
How does a neuron multiply?
Adult CNS neurons do not multiply. During development cells bud off from stem cells around the neural tube, controversially this is also thought to occur rarely in the adult CNS.
What synapse is more common in embryonic nervous tissue than in adults?
They permit the exchange of guiding clues during early neuronal development so that neurons can connect properly with one another.
Most neurons lack centrioles This observation explains?
Neurons lose their centrioles during differentiation, and they become incapable of undergoing cell division.
What are some examples of stretch reflexes during hypoactive?
Coma, neurosyphilis, chronic diabetes mellitus
What part of the nervous system would be responsible for moving your hand from a burner?
A reflex is a rapid, involuntary response to a stimulus. Most reflexes are spinal reflexes with pathways that traverse only the spinal cord. During a spinal reflex, information may be transmitted to the brain, but it is the spinal cord, and not the brain, that is responsible for the integration of sensory information and a response transmitted to motor neurons. If you touch a very hot burner, your hand will move away faster than information goes to your brain to tell you "Hey, that is hot!"
Does number of neurons remain constant?
No. In fact they reduce in number during life.
