How does information flow through your nervous system as you pick up a fork?
Your central nervous system's hungry brain activates and guides the muscles of your arm and hand through the peripheral nervous system's motor neurons. When you pick up the fork, your brain processes the information that was sent from your sensory nervous system, helping it guide your fork to your mouth. This process starts with sensory input, then to interneuron processing and ends with motor output.
Is it true that left handed people are more likely to be good artist?
Yes. The left side of the brain is the base of creativity, and the left side of brain controls the left hand, so the nerves from the brain go to the left hand. Short answer: yes, if you are right- handed good luck
What is the difference between the the motor neuron and the sensory neuron based on their function?
Motor neurons are responsible for transmitting signals from the central nervous system to muscles or glands, allowing for voluntary movement or secretion. On the other hand, sensory neurons detect information from the external environment or the body and transmit it to the central nervous system, enabling us to perceive sensory stimuli such as touch, temperature, pain, or sound. In summary, motor neurons control movement and actions, while sensory neurons provide information about the external world to the brain.
How does the body receive information from the environment?
The senses are composed of sensory receptors and, when activated, it sends a electrochemical signal to an attached neuron. That neuron does the same to another attached neuron and eventually the signal reaches the brain, where you process the information. If you were to touch a hot stove a sensory nerve specified for a temperature rise would be activated and send a signal to the brain and in a split second you take your hand or finger off before you burn your skin. The tongue (as well as other parts of the mouth) has taste receptors that sense a specific taste. The nose has much of the same thing, but instead of tasting a solid or liquid, it tastes or smells gas particles. The ear is more complicated. When there is sound or vibration in the air, the sound waves travel inside the air and eventually to the ear drum. It vibrates and sends a signal to the brain. The eyes have optical nerves that respond to what wavelength of light is penetrating it.
How does a muscle tissue lie in relation to the body part it causes to move?
A muscle sits on a bone that is connected with cartilage. We have nerves connecting everything in our body together so we can feel things. If our brain says, "Close your eyes, or Lift your head, or raise your hand....." then the muscles connected to those nerves will respond to those brain messages. For example.... If one is playing soccer outside and you want to kick the ball, the brain sends signals to those nerves to stop and start those muscles when you are kicking or running or standing still.
WHAT IS THE DIFFERENCE BETWEEN THE ANTERIOR and POSTERIOR ROOT OF THE SPINAL NERVES?
The cerebrospinal nervous system consists of the brain, spinal cord and the peripheral nerves given off by these to the outer parts of the body. 31 pairs of nerves emerge from the spinal cord. Each nerve has 2 roots - 1 anterior(at the front of the spine) and 1 posterior (at the back of the spine) carrying sensory nerves. Motor nerves carry impulses to the muscles, & have the responsibility for bodily movement. On the other hand, sensory nerves are responsible for carrying sensory impulses which provide the brain with information about sensation i.e. hot and cold.
What are the functions of afferent and efferent nerves?
Afferent nerves carry sensory information from the body to the brain, allowing us to sense touch, temperature, pain, and other stimuli. Efferent nerves, on the other hand, transmit signals from the brain to the muscles and glands, enabling movement and physical responses.
Why does your hand hurt?
their are nerves in your hand and sends messages to your brain
What causes your hand to be hot when you touch a spoon that is in boiling water?
Sensory nerves.
Path way of the message to the nervous system?
The stimuli will be picked up by the sensory neurons then nerve impulses travel to your spinal cord. Those nerve impulses return to motor neurons that will react (like you pull your hand away, or you yell) as you react the nerve impulses travel to your brain.
What influences the nervous and endocrine systems on behavior?
A thorough discussion of how your body works best begins with an overview of your nervous and endocrine systems, as these two organ systems act as co-directors of all of the activities that occur in your body. To put it simply, your nervous and endocrine systems continuously monitor the well-being of each of the billions of cells in your body, and they continuously take action through messenger systems to keep all of your cells as healthy as possible. Though your nervous and endocrine systems share the director's seat of your body, they fulfil their roles in completely different ways. Your nervous system senses and controls every part of your body through its many nerves. Sensory receptors located throughout your body constantly send information through nerves to your brain; your brain digests this information; your brain then decides on appropriate action, and executes the action by sending additional information out to the target cells through other nerves. For example, if you accidentally touch a hot pan, sensory receptors register pain almost instantaneously, this information travels through nerves to reach your brain, your brain understands that your hand is in danger of being injured in its current position, and your brain sends information down other nerves that tells your muscles to jerk your hand away from the pan. source:internet
What is the Role of brain in reflex action?
Reflex actions are sudden responses, which do not involve any thinking. For example, when we touch a hot object, we withdraw our hand immediately without thinking as thinking may take time which would be enough to get us burnt. The sensory nerves that detect the heat are connected to the nerves that move the muscles of the hand. Such a connection of detecting the signal from the nerves (input) and responding to it quickly (output) is called a reflex arc. The reflex arcs −connections present between the input and output nerves − meet in a bundle in the spinal cord. Reflex arcs are formed in the spinal cord and the information (input) reaches the brain. The brain is only aware of the signal and the response that has taken place. However, the brain has no role to play in the creation of the response.
What is an example of responding to information in the nervous system?
If you accidentally touch something very hot and reflexively pull away, that action happens within the nerves of the hand, arm and spinal chord without the involvement of the brain. It does not involve any higher brain functions; it is indeed reflexive and happens within the nerves outside of the brain.
What role do nerves play in your body?
Nerves give you feeling all over your body. Pain, numbness, being able to feel; it's all from nerves. Nerves carry signals to and between part of your body. When you touch something hot, a sensation goes through the hand to the nerves, and the nerves give signals to the brain. The brain recognizes it is hot, so the brain sends signals to the nerves in your hand to withdraw.
How does the muscle respond in reflex action?
Nerves are bundles of axons and their sheaths of connective tissue that extend from the CNS to peripheral structures,Nerves are responsible for stimuli communication and responceThe Central nervous system CNSBrainSpinal CordThe Prephrial nervous system PNSCranial nerves, which arise from the brain Sensory/ afferent transmits STIMULI from the sensory organs to the CNSMotor/ efferent-transmits action potentials from the CNS to effector organs when a Stimuli is recieved causing some sort of reaction.Spinal nerves, which arise from the spinal cordIf the sensory Stimuli was an itch on the tip of your nose the motor action potential generated would send your hand to your nose to scratch the itch.
What are afferent and efferent neurons and inter neurons?
These neurons are classified by the direction in which they send their messages. Afferent neurons are typically sensory neurons--neurons which send information to the brain and spine. They send information about the body and immediate environment. Efferent neurons are typically motor neurons, sending information from the brain and spine to the rest of the body. They allow the main control system a way to act on the body. Another way to distinguish these two is to think of afferent nerves as 'approaching' the brain (A) and efferent nerves as 'exiting' the brain (E). Interneurons are relay neurons and their signals, connecting efferent and afferent neurons in network. They can link up the same types or different types of neurons, meaning connecting sensory neurons together, motor neurons together, or the different types together. The simplest example of these three types working in unison is a reflex arc (which is what is activated when you hurt yourself, like stepping on a pin or burning your hand). The sensory/afferent neuron detects pain and signals the interneuron. Simultaneously, the interneuron sends a signal to your efferent/motor neurons to retract your hand/leg/whatever, while also sending a message to the brain. This is why you pull back before you feel pain :).
