Homeostasis

Which of the following is NOT a type of sensory receptor?

• Mechanoreceptor

• Photoreceptor

• Hydroreceptor

• Chemoreceptor

Which sensory receptor is responsible for detecting temperature changes?

• Mechanoreceptors

• Thermoreceptors

• Chemoreceptors

• Photoreceptors

Why do we have a blind spot in each eye?

• The lens distorts the image

• The retina is damaged

• There are no photoreceptors where the optic nerve leaves the eye

• The iris blocks light in that area

Why do objects appear grey in our peripheral vision?

• The optic nerve blocks colour perception

• There are more rods than cones in the peripheral retina

• The cornea absorbs colour wavelengths

• Light does not reach the retina properly

What is homeostasis?

• The ability of an organism to grow rapidly

• The method the body uses to sense pain

• The ability of the eye to adjust focus

• The process of the body maintaining a stable internal environment

Which organ systems are primarily responsible for maintaining homeostasis?

• Skeletal and muscular systems

• Nervous and endocrine systems

• Digestive and respiratory systems

• Circulatory and lymphatic systems

What is the first step in the stimulus-response model?

• Control centre processes the information

• Effector carries out a response

• Receptors detect a stimulus

• Brain releases hormones

Which system transmits electrical signals from receptors to the brain?

• Circulatory system

• Digestive system

• Nervous system

• Lymphatic system

What is the role of effectors in the stimulus-response model?

• Detect environmental changes

• Process information in the brain

• Respond to signals from the brain

• Store sensory information

What type of receptor detects pain?

• Photoreceptors

• Chemoreceptors

• Mechanoreceptors

• Nociceptors
