Control and Coordination in Mammals Quiz

During a science experiment, Maajed is testing how different types of receptors in the body respond to various stimuli. He decides to poke a balloon to see which receptor is activated by the mechanical stimulation. What type of receptor responds to mechanical stimulation?

• Chemoreceptors

• Photoreceptors

• Mechanoreceptors

• Thermoreceptors

During a science class, Ahmad is curious about where touch receptors are primarily located in the human body.

• In the carotid artery

• In the brain

• In the dermis of the skin

• In the cochlea

During a biology class, Mia learned about the resting potential of a neurone at rest. What is the resting potential of a neurone at rest?

• -70 mV

• -90 mV

• +40 mV

• 0 mV

Leem and Mia are studying how neurons communicate. They learn that certain ions are primarily involved in establishing the resting potential of a neuron. Which ions are they discussing?

• Calcium and magnesium

• Sodium and potassium

• Iron and copper

• Chloride and bicarbonate

Maryam is studying how neurons communicate. She learns that during depolarization of a neurone, something important happens. What is it?

• Potassium ions rush in

• Sodium ions rush out

• Sodium ions rush in

• Chloride ions rush in

Rohan is studying how cells maintain their environment. What is the role of the sodium-potassium pump?

• To generate action potentials

• To facilitate diffusion

• To maintain resting potential

• To transmit impulses

During a biology experiment, Dana discovered that there is a specific level of stimulation needed to trigger a response in a neuron. What is this threshold of stimulation?

• The maximum potential difference

• The resting potential of a neurone

• The point of maximum sodium influx

• The minimum intensity required to trigger an action potential

What occurs during the refractory period when Nora is studying for her biology exam?

• The resting potential is established

• The neurone is highly excitable

• The action potential is generated

• The neurone cannot conduct another impulse

While studying in the lab, Ali noticed that the temperature of the water in the beaker was changing. He wondered which type of receptor is responsible for detecting temperature changes.

• Chemoreceptors

• Thermoreceptors

• Photoreceptors

• Mechanoreceptors

Evelyn is conducting an experiment in her biology class to understand how different sensory receptors work. She learns that some receptors are specialized to recognize specific types of stimuli. What is the primary function of chemoreceptors?

• To detect light

• To sense temperature changes

• To respond to mechanical stimuli

• To recognize chemical stimuli
