What is a sensory receptor?
Sensory receptors are parts of the nervous system that give us information about our external and internal environment

Superior Oblique Muscle
The superior oblique muscle rotates the top of the eye towards the nose and, to a lesser extent, moves the eye downwards

What are the main portions of the ear called?
external, middle and inner

Proprioceptors
These receptors detect body and limb movements and include only the somatic sensory receptors within joints, muscles and tendons

What does the external ear consists of?
Auricle and external auditory meatus

Define the term " modality of stimulus"
This is the stimulating agent. Some sensory receptors only respond to temperature changes and some respond to chemical changes. There are 5 types: chemoreceptors, thermoreceptors, photoreceptors, mechanoreceptors, (baroreceptors), nocireceptors.
