What else can I help you with?
In the control of respiration, which of the following is NOT TRUE?
Respiration responds to smaller changes in the concentration of oxygen than carbon dioxide
What are cell called that detect changes?
Cells that detect changes are called sensory cells or receptor cells. These specialized cells are equipped with receptors that can sense various stimuli such as light, sound, pressure, temperature, and chemicals. They transmit this information to the central nervous system for processing and response.
What are some ways that the human body responds to internal changes such as the presence of excess salt?
First of all, the change in internal conditions is registered by a chemo-receptor, like in the case of excess salt. This receptor in turn releases kinases, which signal the cell to produce a signalling molecule that will affect another cell's receptor or it's own receptor, depending on the circumstances. This chain reaction continues until it reaches a final effector cell which tackles the problem of higher salt concentration, like in this case, vasopressin would be released to dilate the blood vessels so that larger volume of water would flow. This volume is retained by the nephrons in kidney by reabsobing water from the urine formation process. The higher volume of water will dilute the excess salt and homeostasis would be maintained.
How a drug interacts with a receptor?
A drug interacts with a receptor by binding to specific sites on the receptor, leading to changes in the conformation or activity of the receptor. This interaction can either activate or inhibit the receptor's function, ultimately affecting downstream signaling pathways and physiological responses within the body. The strength and specificity of this interaction determine the drug's effectiveness and potential side effects.
Which receptor in sensitive to changes in pressure?
The mechanoreceptor is the receptor sensitive to changes in pressure. It is responsible for detecting mechanical stimuli such as touch, pressure, and vibration and relaying this information to the brain.
The receptor senses changes in the environment and responds by send information to the control center along what?
The receptor senses changes in the environment and responds by sending information to the control center along nerve impulses or chemical signals.
What receptor can detect changes in hydrogen ion concentration?
The receptor that can detect changes in hydrogen ion concentration is the chemoreceptor, specifically the peripheral chemoreceptors located in the carotid bodies and aortic bodies. These chemoreceptors can sense changes in pH levels caused by alterations in carbon dioxide levels and subsequently regulate breathing to maintain homeostasis.
What senses changes in the environment and responds by sending information to what?
The Receptor senses changes in the environment and responds by sending information to the Control Center along the Afferent.
In the control of respiration, which of the following is NOT TRUE?
Respiration responds to smaller changes in the concentration of oxygen than carbon dioxide
Cell contains receptor proteins for various chemicals?
Receptor proteins on the cell surface bind to specific chemicals, triggering intracellular signaling pathways that initiate cellular responses. These responses can include changes in gene expression, enzyme activity, or cell behavior based on the type of chemical detected by the receptor. This process plays a critical role in cell communication, regulation, and homeostasis.
Which receptor is likely to detect changes in carbon dioxide and oxygen concentration in the blood?
The receptors that are likely to detect changes in carbon dioxide and oxygen concentration in the blood are chemoreceptors located in the aorta and carotid arteries. These chemoreceptors detect changes in the pH of the blood and send signals to the brain to regulate breathing heart rate and other bodily functions. The receptors are sensitive to the following: Carbon dioxide concentration Oxygen concentration pH of the bloodThe chemoreceptors are located in the walls of the aorta and carotid arteries and are sensitive to the changes in carbon dioxide and oxygen concentrations. When the concentrations of these two gases change the chemoreceptors send signals to the brain which then responds with appropriate adjustments in breathing rate and heart rate.
What are the functions of a neuron?
Senses changes both in and outside the body (the sensoryfunction).Interprets and explains the changes (the integrativefunction).Responds to the interpretation by making muscles interact and glands secrete hormones or other chemicals into the bloodstream (the motor function).
Are receptor that can respond to changes in pressure?
Mechanoreceptors
What is a type of receptor that responds to changes in stretch of skeletal muscle and initiates a stretch reflex?
Muscle spindle receptors which are located in the belly's of muscles measure length of stretch and speed of change. They send this afferent neural information to the posterior horn of the spinal cord where and interneuron interprets the information and if the stretch is ballistic (if it changes length too rapidly) it will trigger an efferent motor unit, or many motor units, through the anterior horn of the spinal cord to contract the muscle.
What is the variable that responds to changes?
The dependent variable is the variable that responds to changes in an experiment or study. It is what is being measured or tested to see if it is affected by the manipulation of the independent variable.
How a plant responds to changes in the seasons?
it wear coats
Does a receptor detect change in the environment?
Yes, receptors are specialized cells or proteins that detect changes in the environment or within the body, such as changes in temperature, pressure, or the presence of chemicals. They transmit this information to the nervous system for further processing and response.
