how are sensory systems, the CNS, the effectors such as muscles related?
|
Sensory receptors recieve information from the enviorment, then transduces the information to sensory neurons. Sensory neurons sends the information in the form of membrane potentials to the CNS. CNS integrates the information and sends signals to muscles (Effectors).

|
How are different levels of information sent by a certain receptor cell?
|
Based upon the level or intensity of infromation received (sound, light, etc) sensory receptors will change their the firing rate of action potentials sent to the brain.
--higher sounds induce a higher frequency of action potential than others. |
|
|
statocyst
|
A sensory organ of many arthropods that detects the animal’s orientation in space.It contains a small calcium-rich structure.

how is information passed in the ear?
|
the mammalian outer ear transmits sound waves from the enviornment to the middle ear; the middle ear amplifies these waves enough to stimulate the hair cells within the cochlea of the inner ear.
|
|
|
compound eye
|
An eye formed of many independent light-sensing columns (ommatidia); occurs in arthropods.
|
|
|
camera eye
|
The type of eye in vertebrates and cephalopods, consisting of a hollow chamber with a hole at one end (through which light enters) and a sheet of light-sensitive cells against the opposite wall.

|
how we hear
|
the outer ear recieves signals, this signal travels to the middle where it is taken take up through the tampanic membrane through the ossicles where the message is recived by cochlea which have sterocillia that traducess sound into action potentials.
