How does massage therapy affect the central nervous system?
It depends on the techniques that are used. Some techniques will stimulate the nervous system (such as some forms of tapotment). This is useful before an athletic event, because your muscles are stimulated. Some techniques act like a sedative, and are very relaxing (such as kneading, petrissage and effleurage). However, the effects of massage are more effective on the ANS (automatic nervous system) which houses the PNS and SNS. (parasympathetic nervous system, and sympathetic nervous system, respectivley).
What makes people smile?
Human beings are actually the only created beings that have the ability to reason and logically process information first before they respond, which is different from animals that generally respond to environmental stimuli based on biological defaults. The human aspect of reasoning is what negates the theory of evolution in that if all creatures evolved the same way, the animals would be able to reason as human beings but as we all know, they do not possess this special quality which is why they don't complain about sleeping on the floor or sleeping in the dog house. Reasoning and smiling is a capacity that is restricted to humans.AnswerWe smile because the world we live in is beautiful,We smile because we are loved,We smile because we understand something, even if it is so small.Finally we smile because God gave us the means and the reason to do so.AnswerThe question of why we smile is still being studied and observed by our scientists. However current line of evidence suggests that human smiling is an automatic, cross cultural response to certain stimuli-internal and/or external-that produce certain pleasant reactions in the person smiling. Further evidence points to smiling being both instinctive and hardwired while also learned and social. A study of feral children who lived in isolation from human contact and have remained unaware of human social behavior and unexposed to language found that such children were unable to smile, even after contact was established. This suggests that social interaction plays a large role in either smiling as a reflex, or helping to biologically develop the brain to be able to be able to pick up this kind stimuli reflex.On the other hand, since 2001 and since application of new scanning technologies, doctors have been able to observe babies exhibiting facial expressions in the womb. With the corners of the mouth turned up and the cheeks bulging, obstetrician Stuart Campbell, who's in charge of this new discovery, says, "what's behind the smile, of course, I can't say, but… I think it must be some indication of contentment in a stress-free environment" the 4D scanner, which also produces 3D images that move in real time, shows that babies start making finger movements at 15 weeks, yawning at 18 weeks, and smiling, blinking, and crying at 26 weeks. After birth, infants do not usually smile until they are 6 weeks old, creating a further interest to survey the womb and why there is this gap of time where no smiling occurs, perhaps because the infant must adjust to its new, less content surroundings. This new information on the subject suggests that perhaps smiling is a reflex to positive feelings, while at the same time can also be a response to hearing social communications from inside the womb. Those and other findings further suggest that non-verbal communication is a significant aspect of smiling, therefore forming the first steps to human language.Broken down further, smiling involves both a chemical and biological process. The brain secretes chemicals from neurotransmitters including Serotonin and Dopamine that causes the parasympathetic nervous system (PNS) and the sympathetic nervous system (SNS) to react to environmental stimuli that individuals process unconsciously through the five senses of: seeing, hearing, touching, smelling, and tasting. As a result, if something is amusing or enjoyable the facial muscle movements results in creating smiles that are activated for various reasons. Things such as hearing amusing jokes, watching a person accidentally doing something amusing, and other funny scenarios all contribute to what makes people smile.As a matter of fact, we're laughing just thinking about it!AnswerCause: Something their mind responds to.Reaction: Facial muscles move and the smile is created.
What is the structural difference between the CNS and the PNS?
The central nervous system (CNS) consists of the brain and spinal cord, while the peripheral nervous system (PNS) includes nerves outside of the CNS. The CNS acts as the main control center, while the PNS connects the CNS to the rest of the body.
Is the brain part of the CNS or the PNS?
part of the CNS
What connects the brain to PNS?
The nervous system connects the brain to the peripheral nervous system (PNS) through the spinal cord. The spinal cord serves as a pathway for communication between the brain and the rest of the body, allowing for the transmission of signals to control body functions and movements.
What is the PNS system?
The peripheral nervous system (PNS) consists of all the nerves outside of the brain and spinal cord. It is responsible for transmitting information between the body and the central nervous system, allowing for sensory perception and motor function. The PNS includes sensory nerves that convey information to the brain and motor nerves that control muscle movement.
What does the PNS control and what does it allow you to do?
The peripheral nervous system (PNS) controls all the nerves outside the central nervous system (CNS), connecting the CNS to the limbs and organs. It is responsible for transmitting sensory information to the brain and relaying motor commands from the brain to the body. This allows you to perform voluntary actions like moving your arms and legs, as well as involuntary functions such as regulating heartbeat and digestion. Overall, the PNS plays a crucial role in enabling communication between the body and the brain.
Is the majority of the nervous system contained in the CNS or the PNS?
the PNS as the cental nervous system only consists of the brain and spinal cord. where as the rest of the body is covered by all the nerves which are included in the PNS
What does the autonomic system of the PNS control?
Heart beat
How do the CNS and the PNS interact?
The central nervous system (CNS) consists of the brain and spinal cord, while the peripheral nervous system (PNS) includes nerves outside of the CNS. The PNS relays information to and from the CNS through sensory and motor neurons. The CNS processes the information and sends out responses through the PNS to regulate activities in the body.
List the structures of the CNS and PNS?
Peripheral Nervous System (PNS)Contains all nerves outside of the brain & spinal cord.Somatic Nervous System (Voluntary)Two types: Sensory (or afferent) and motor (or efferent) nerves
What are the components of PNS?
The peripheral nervous system (PNS) comprises nerves outside the brain and spinal cord. It includes sensory nerves (transmitting sensory information to the central nervous system) and motor nerves (transmitting commands from the brain to muscles and glands), as well as the autonomic nervous system (regulating involuntary bodily functions).
How do you functions of the CNS and the PNS differ?
The central nervous system (CNS), comprising the brain and spinal cord, is responsible for processing and integrating sensory information, coordinating bodily functions, and facilitating higher cognitive functions such as thinking and decision-making. In contrast, the peripheral nervous system (PNS) consists of nerves outside the CNS that connect the brain and spinal cord to the rest of the body, facilitating communication between the CNS and limbs or organs. While the CNS acts as the control center, the PNS functions as the relay system, transmitting signals to and from the CNS to enable bodily responses.
In human anatomy what is PNS?
PNS stands for Peripheral Nervous System. The PNS connects the Central Nervous System (in the brain and spinal cord) to the rest of the body. It is divided into the somatic nervous system and the autonomic nervous system.
