You’d want to run away, and fast! One part of your nervous system makes sure you can run to safety. This part is called
the sympathetic nervous system
. When the sympathetic nervous system turns on, your heart beats faster and more blood gets pumped to your muscles so you can put up a fight or run like crazy.
How does the nervous system control running?
The more you run in a certain way,’ he says, ‘the greater the number of neurons that attach to the muscle, the stronger this connection becomes, the quicker this messaging goes to the brain, the more muscle gets recruited, the faster the movement. ‘
What controls the nervous system quizlet?
The control center for the entire nervous system, it is the main network of coordination and control for the entire body. It consists of
the brain
(encephalon) and the spinal cord, which are protected and encased in bone. The brain and the spinal cord are continuous with each other at the foramen magnum.
What is nervous system quizlet?
The nervous system is
the master coordinating system of the body
. Every thought, action, and sensation reflext its activity. The structures of the nervous system are described in terms of 2 principal divisions-the central nervous system (CNS) and the peripheral nervous system (PNS).
What part of the nervous system is responsible for functions like walking and running?
The cerebellum
— also called the “little brain” because it looks like a small version of the cerebrum — is responsible for balance, movement, and coordination. The pons and the medulla, along with the midbrain, are often called the brainstem.
What is CNS system?
What is the central nervous system? The central nervous system (CNS)
controls most functions of the body and mind

How does the nervous system control human behavior?
A vast network of nerves
sends electrical signals to
and from other cells, glands, and muscles all over your body. These nerves receive information from the world around you. Then the nerves interpret the information and control your response.
Do nerves run through muscles?
The
neuromuscular system
includes all the muscles in the body and the nerves serving them. Every movement the body makes requires communication between the brain and the muscles. The nervous system provides the link between thoughts and actions by relaying messages from the brain to other parts of the body.
What is the autonomic nervous system quizlet?
What is the function of the autonomic nervous system?
a control system that acts largely unconsciously and regulates bodily functions
such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.
What is somatic control?
The somatic nervous system is a component of the peripheral nervous system
associated with the voluntary control of the body movements via the use of skeletal muscles
. … The somatic nervous system consists of both afferent (sensory) and efferent (motor) nerves [1].
Where is the nervous system located quizlet?
The CNS consist of
the brain and the spinal cord
, and the peripheral nervous system consists of peripheral nerves, which are located throughout the rest of the body.
What does the central nervous system do quizlet?
The central nervous system is that part of the nervous system that consists of the brain, brain stem, and spinal cord. -The CNS is the main control center of the body – it
takes in sensory information, organizes and synthesizes data, then provides direction for motor output to the rest of the body
.
What is the nervous system composed of quizlet?
The central nervous system is composed of:
The brain and spinal cord
. The peripheral nervous system is composed of: The cranial and spinal nerves that travel to all parts of the body.
What are nerves and what do they do quizlet?
Nerves that connect all parts of the body to the brain
. Divided into two portions; Somatic nervous system and autonomic nerves system. Within the spinal cord are cells with short fibers that connect the sensory nerves with the motor nerves. Bypassing the brain.
Does the central nervous system control the peripheral nervous system?
The peripheral nervous system (PNS) is the division of the nervous system containing all the nerves that lie outside of the central nervous system (CNS). The primary role of the PNS
is to connect the CNS to the organs, limbs, and skin
.
What does the cerebellum control?
The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for
coordinating voluntary movements
. It is also responsible for a number of functions including motor skills such as balance, coordination, and posture.
What is the central nervous system made up of?
The brain and the spinal cord
are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.
What is autonomic and somatic nervous system?
Somatic Nervous System is the
one that allows conscious (voluntary) control of skeletal muscles
. Autonomic N. S. has the unconscious (involuntary) control of the body and it has 2 branches, the Sympathetic and Parasympathetic NS.
What is the autonomic nervous system?
Your autonomic nervous system is
the part of your nervous system that controls involuntary actions
, such as the beating of your heart and the widening or narrowing of your blood vessels. When something goes wrong in this system, it can cause serious problems, including: Blood pressure problems.
What is parasympathetic neural system?
The parasympathetic nervous system
predominates in quiet “rest and digest” conditions
while the sympathetic nervous system drives the “fight or flight” response in stressful situations. The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination.[1]
What are the 4 main parts of the nervous system?
The nervous system consists of
the brain, spinal cord, sensory organs
, and all of the nerves that connect these organs with the rest of the body.
What are the 2 types of nervous systems?
- The central nervous system is made up of the brain and spinal cord.
- The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
What are the 4 main functions of the nervous system?
- Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature. …
- Programming of spinal cord reflexes. An example of this is the stretch reflex. …
- Memory and learning. …
- Voluntary control of movement.
What branch of the nervous system controls this response?
The
sympathetic division
of the autonomic nervous system regulates the flight-or-fight responses.
What is sympathetic and parasympathetic?
The autonomic nervous system comprises two parts- the sympathetic and parasympathetic nervous system. The sympathetic nervous system
activates the fight or flight response during
a threat or perceived danger, and the parasympathetic nervous system restores the body to a state of calm.
What is the parasympathetic nervous system quizlet?
The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is
to control homeostasis and the body’s rest-and-digest response
. … Its general action is to mobilize the body’s fight-or-flight response.
Is the autonomic nervous system part of the central nervous system?
The brain and spinal cord make up the
central
nervous system. The peripheral nervous system is comprised of the somatic and autonomic nervous systems. The somatic nervous system transmits sensory and motor signals to and from the central nervous system.
Is part of the sympathetic nervous system quizlet?
The sympathetic nervous system (SNS) is part of
the autonomic nervous system (ANS)

Which part of the body is the control center for the nervous system?
The brain
is the body’s “control center.” The CNS has various centers located within it that carry out the sensory, motor and integration of data. These centers can be subdivided to Lower Centers (including the spinal cord and brain stem) and Higher centers communicating with the brain via effectors.
Which nerves cause the movement of muscles?
Skeletal muscles are attached to bones and produce movement at the joints. They are innervated by
efferent motor nerves and sometimes by efferent sympathetic and parasympathetic nerves
. Every movement of the body has to be correct for force, speed, and position.
What is the somatic nervous system quizlet?
The somatic nervous system (SoNS or voluntary nervous system) is
the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles
. The SoNS consists of afferent nerves or sensory nerves, and efferent nerves or motor nerves.
What does the sympathetic nervous system control?
The sympathetic nervous system directs the
body’s rapid involuntary response to dangerous or stressful situations
. A flash flood of hormones boosts the body’s alertness and heart rate, sending extra blood to the muscles.
