What are the answers for the incredible journey a visualization exercise for the nervous system?
The Incredible Journey: A Visualization Exercise for the Nervous System is part of an anatomy assignment in many school districts. This is a paragraph by paragraph reading assignment that walks student through various systems of the human body. Some of the answers to the nervous system portion are; the brain, the sensory organs, and the spinal cord.
Is a hypothalamus similar to a thermostat?
Yes, the hypothalamus is similar to a thermostat because it controls the body temperature. The thermostat in a home or in a car is what controls that things temperature.
What are the type of nerve cells on retina that allow you to see dim light?
These nerve cells are called rods.
Why might the symptoms of a degenerative disease of the nervous system be difficult to treat?
nervous system is the coordinating centre of the body.so if any person is suffering through the degenerative disease of nervous system , it is difficult to treat as whole body is affected by it.
What Exerts the most direct control over the functioning of the autonomic nervous system?
The reticular formation in the brain stem
What are The worst possible combination of central nervous system depressants are?
Alcohol and barbiturates. However, alcohol combined with just about any other CNS depressant will kill you.
nerves
The radial nerve runs along the thumb-side edge of the forearm.
It gives sensation to the back of the hand from the thumb to main knuckle of the back surface of the ring and middle fingers.
The median nerve travels through carpal tunnel.
Sensory branch to the thumb, index finger, long finger, and half of the ring finger.
Motor branch to the thenar muscles(abductor pollicis brevis, flexor pollicis brevis, opponens pollicis) of the thumb.
The ulnar nerve travels Guyon's canal.
Sensory branch to the little finger and half the ring finger.
Motor branch to adductor pollicis and hypothenar muscle(abductor digiti minimi, flexor digiti minimi brevis, opponens digiti minimi).
My Eye twitches and your muscles twitch randomly And your coordination is off What is that?
It depends on how long this has been occurring, your age and the severity of your symptoms. There could be some neurological involvement, including the possibility of multiple sclerosis or a tumor. If this does not improve, it is important to have a physician do a complete examination. Check your insurance to see if you need a referral to a neurologist, as that is the best place to start. Otherwise, you may need to see your GP to refer you to a specialist. Do it sooner, than later.
What is the same as a sensory nerve?
The peripheral nervous system is the same as the sensory nerves. These are the nerves which are responsible for the various senses.
Does a conch have a nervous system?
Yes, they do. All gastropods have nerve cords with a "brain" of some sort consisting of three pairs of ganglia organized in a ring.
What subfields in psychology focuses on how the brain and the nervous system determine behavior?
Behavioral Neuroscience
What is the basing building blocks of the nervous system?
A neuron i.e. a nerve cell is the basic building block of nervous systenm
Can the nervous system affect balance?
Yes, both the central and peripheral nervous systems have a role in maintaining balance.
What part of nervous system carry all spinal nerves?
The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let's take a look at the peripheral nervous system.
Peripheral Nervous SystemThere are two types of cells in the peripheral nervous system. These cells carry information to (sensory nervous cells) and from (motor nervous cells) the central nervous system (CNS). Cells of the sensory nervous system send information to the CNS from internal organs or from external stimuli.Motor nervous system cells carry information from the CNS to organs, muscles, and glands. The motor nervous system is divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system controls skeletal muscle as well as external sensory organs such as the skin. This system is said to be voluntary because the responses can be controlled consciously. Reflex reactions of skeletal muscle however are an exception. These are involuntary reactions to external stimuli.
The autonomic nervous system controls involuntary muscles, such as smooth and cardiac muscle. This system is also called the involuntary nervous system. The autonomic nervous system can further be divided into the parasympathetic and sympathetic divisions.
The parasympathetic division controls various functions which include inhibiting heart rate, constricting pupils, and contracting the bladder. The nerves of the sympathetic division often have an opposite effect when they are located within the same organs as parasympathetic nerves. Nerves of the sympathetic division speed up heart rate, dilate pupils, and relax the bladder. The sympathetic system is also involved in the flight or fight response. This is a response to potential danger that results in accelerated heart rate and an increase in metabolic rate.
Thats all I know about a nervous system and spinal nerves hope it is helpful.
Whai is an example of a retail store that appeals to physiological need?
Physiological needs are food, water, breathing, and homeostasis. Example of retail stores that appeal to customers' physiological needs include WalMart, Target, and Sear's.
What are the 2 types of nervous systems in the body and what do they control?
the two main types of nervous systems would be the parietal nervous system and the central nervous system. The CNS controls most voluntary movements, while the parietal system controls involuntary actions such as breathing and the fight and flight response.
Is bronchoconstriction sympathetic or parasympathetic?
Bronchoconstriction is due to an activation of parasympathetic nervous system.
When is epinephrine considered to be a neurotransmitter and when is it considered to be a hormone?
it's a hormone when it is produced by the adrenal gland and a nuerotransmitter when it is secreted by a nueron.
How does the nervous system usually communicate with the rest of the body?
Peripheral nerves carry information to the CNS, which processes the information and sends a message back telling the body how to respond.
medulla oblongata
What are effectors of the nervous system?
The effectors of the nervous system are muscles and glands. They respond to nervous stimuli.
