feelings. This can be termed feedforward as you take these steps to avoid a low energy state before it happens. Negative feedback systems require receptors to detect change, a control centre to receive the information and process the response, effectors to reverse the change and re-establish the original...

2. The general sense organs consist of microscopic receptors widely distributed throughout the body in the skin, mucosa, connective tissues, muscle tendons, joints, and viscera. The special senses are characterized by receptors grouped...
the Sensory System It would be a miserably bleak existence if it wasn’t for our senses. Our senses take in information from outside (and inside too) our bodies and convert it to a form our nervous systems can understand. Our sensory systems work kind of like computer systems. In a computer system there...

‘feed forward’ as you are taking steps to avoid a low energy state before it has even happened.
Negative feedback systems require the following; receptors to detect change, a control centre to receive the information and process the response, and effectors to reverse the change and re-establish the original...
SOMATIC & SPECIAL SENSES
All senses work in basically the same fashion. Special sensory receptors collect information from the environment and stimulate neurons to send a message to the brain. There the cerebral cortex forms a perception, a person's particular view of the stimulus...

Discuss the role of negative feedback in living organisms and how it benefits these living organisms? (25 marks)
Negative feedback is the process by which changes occur to bring an organism’s internal environment back to the normal level.
One example of negative feedback in a living organism is the...
