The receptor
changes in the environment and responds by sending information to the control center along the afferent pathway. The control center analyzes the input, determines the appropriate response, and activates the effector by sending information along the efferent pathway.
What transmit information from receptors to control center?
Receptors: Thermoreceptors detect changes in
body temperature
. For example, thermoreceptors in your internal organs can detect a lowered body temperature and produce nerve impulses that travel to the control center, the hypothalamus.
What sends a message to the control center?
A structure (sensory nerve ending) of the
nervous
system that detects stimuli. … The control center will then send an electrochemical message along the efferent pathway of nerves to the effectors (muscles and glands).
What is the name of the pathway that receives information from the control center?
Regardless of the system used, if communication flows toward the control center from the receptor, it is termed an afferent pathway. If information flows from the control center to the effector, it is termed an
efferent pathway
.
Which feedback system structure provides input to the control center?
The sensory receptor or sensor
provides input to the control center. Control center is the body structure that determines the normal range of the variable, or set point.
How do nerves transmit information?
The nerve cell, or neuron, is the key player in the activity of the nervous system. It conveys information both electrically and chemically. Within the neuron itself, information is
passed along through the movement of an electrical charge (i.e., impulse)
.
What can receptors detect?
Receptors are groups of specialised cells. They can detect
a change in the environment (stimulus ) and produce electrical impulses in response
. Sense organs contain groups of receptors that respond to specific stimuli .
What produces change in a variable?
variable.
the factor or event being regulated
.
stimulus
. produces change in variable.
Where is the control center for body temperature regulation?
Your hypothalamus
is a section of your brain that controls thermoregulation. When it senses your internal temperature becoming too low or high, it sends signals to your muscles, organs, glands, and nervous system. They respond in a variety of ways to help return your temperature to normal.
Which of the following is an example of homeostatic imbalance?
A commonly seen example of homeostatic imbalance is
diabetes
. In a diabetic, the endocrine system has difficulty maintaining the correct blood glucose levels, so diabetics must closely monitor their blood glucose levels, as shown in Figure below.
What part of the brain controls posture and balance?
The cerebellum
controls a number of functions including movement, speech, balance, and posture. But the cerebellum doesn’t work alone. There are several other parts of the brain that also contribute to balance functions, including something known as the vestibular system.
Which of the following is the pathway for voluntary movement?
The corticospinal tract
is the main pathway for control of voluntary movement in humans.
What is the main difference between the pathways for pain and touch?
Touch is the sense by which we determine the characteristics of objects: size, shape, and texture. Pain messages are picked up by
receptors
and transmitted to the spinal cord via small myelinated fibers and very small unmyelinated fibers.
What are examples of positive feedback?
Positive feedback you can give: “
I’m really happy with your determination to finish this project
. I know it wasn’t easy, but I knew you could do it. Your helpful attitude makes it clear that you can continue to take on new challenges and grow with the company. Thank you for your extra effort.”
What are the three main components of a homeostatic control system?
Homeostatic control mechanisms have at least three interdependent components:
a receptor, integrating center, and effector
.
What system is the control center of the body?
The central nervous system
is the master control system and is responsible for the function of everything in your body.
