It's not easy to be sure what is meant here. The sight organ is the eye, and the sound organ is the ear, but these are sense organs, i.e. they contain receptors. The larynx makes sound, and this could be classed as an effector if you shout in response to a stimulus, but you can't really think of sight in this way.
Sense organs is your sight, feel, smell, balance, and taste. All in which are made to keep you alive. So use them
Sight Sound Temperature Hunger/Thirst
Sight, sound, touch, taste, & smell are the "standard list" of external senses.
in the inner ear.a2 Your balance organs are located near to the middle ear. The inner ear is exclusively devoted to sound.
Both require motor neurones to carry the nerve impulse to the effector in order for the muscle to contract carry out an action.
Three examples of visceral effector organs would be the heart, kidney and liver organs. Effector organs are considered to be muscle and glands, like the mouth and stomach.
Muscles or glands which carry out the responses
Motor neurons are able to create a response in effector organs, muscles and glands by sending signals to them.
Sensory. hope that helped.
muscarinic receptor
The brain is the place where signals from the sense organs (eyes/ ears) are converted into what we think of as sight and sound.
Motor Neurones send the impulse from the CNS to the effector muscle
parasympathetic nervous system
two-neuron chain from CNS to effector organs. Parasympathetic and Sympathetic.
No. The I in sight has a long I sound, as in sigh and site.
Physiological antagonist are those substance that have opposing physiological action but act at different receptors
One sense that birds have is sight - and the organs used are eyes.Another sense is sound - they sing to one another - so they have some sort of hearing organ, commonly called ears.
