What describes the parasympathetic division of the autonomic nervous system?
The autonomic nervous system.
What is the origin of most cranial nerves?
cranial nerves arise from the brain inside the cranial cavity.
How does the nervous system coordinate the body's response to stimuli?
It looks across the entire world and sees their best friend and gets really happy
What would Direct stimulation of the motor cortex result in?
It would cause involuntary movement or a sense of touch on the person.
List the division of the autonomic nervous system?
the autonomic nervous system (ANS) includes the peripheal nerves and ganglia on either side of the spinal cord ( note: some textbooks include the ANS as a division pf the peripheal nervous system both ways are correct.)
Is there electricity in your body?
Yes, the nerves act like the wires in your house to send elctrical signals through your body.
What is the central center of the nervous system?
Brain.
The brain is the control center of the body. It consists of three main components: the forebrain, the brainstem, and the hindbrain. The forebrainis responsible for a variety of functions including receiving and processing sensory information, thinking, perceiving, producing and understanding language, and controlling motor function. The forebrain contains structures such as the thalamus and hypothalamus which are responsible for such functions as motor control, relaying sensory information, and controlling autonomic functions. It also contains the largest part of the brain, the cerebrum. Most of the actual information processing in the brain takes place in the cerebral cortex.
The best example of cooperative autonomic effects is seen in controls of the external genitalia. Parasympathetic stimulation causes vasodilation of blood vessels in the external genitalia, and is responsible for erection of the male penis or female clitoris during sexual excitement. Sympathetic stimulation then causes the ejaculation of semen by the penis or reflex contractions of the vagina during an orgasm.
Can Lupus affect the nervous system?
Lupus can also effect the central nervous system, causing seizures, depression, and psychosis
How are the components of the nervous system involved in skeletal muscle movements?
The components of the nervous system involved in skeletal movements are the hemolymph A31.
What are clusters of nerve cell bodies in the peripheral nervous systems?
gangia(n) (pluaral/singular)
What might happen if there was a breakdown in the nervous system?
If your nervous system failed, you would lose feeling of every part of your body. Touch prevents you from destroying your body and tearing it apart. If you lose touch, which is when your nervous system fails, you will unknowingly tear your body to shreds, and your whole body will ultimately fail and collapse. no messages would get sent around your body telling your body what to do.
What does the central nervous system use to determine the strength of a stimulus?
frequncy of action poteinals
What is another name for nerve tissue?
Neurons are the name of the nerve cells. They are ultra-sensitive cells which “fire” communication signals with the central nervous system. They help detect all superficial and some internal sensations, such as itching or pain.
somatic nervous system which is a part of peripheral nervous system.
What part of the brain is controlled by the nervous system?
brain, spinal cord, ganglia, nerves, sensory receptors, neuroglia, neurons.
Why is the reflex reaction important in certain situations?
Without an automatic response to a simple stimulus which does not require mental processing, a human being would not be able to react to its' own functions being harmed in any way. Example: Skin contact with fire, without a response to the flame, your skin would burn.
Strong stimulant that speeds up the nervous system?
A strong stimulant the speeds upthenervous system
A peripheral nation is a country that is often characterized by lower levels of industrialization, economic dependence on more developed nations, and limited access to global markets. These nations typically have weaker economies, less political influence, and may rely heavily on exporting raw materials or agricultural products. In the context of world-systems theory, peripheral nations are contrasted with core and semi-peripheral nations, highlighting their marginal position in the global economic hierarchy.
Why isn't the hair follicle controlled by skeletal muscle?
Because cerebral cortex has too many work already. If we have to think about contolling the hair may be we can be only the porcupine instead of two legs mongky. ^^
What part of the autonomic nervous system calms the body?
both symphataticand parasyphatatic nervouse
