The document discusses sensitivity and coordination in the human body. It covers several topics: - There are two types of stimuli - internal from inside the body and external from outside. A response is the body's answer to a stimulus. - The five senses - sight, smell, hearing, touch, and taste - and the organs associated with each sense. - An overview of the nervous system, including the central and peripheral nervous systems. The central nervous system contains the brain and spinal cord. - Voluntary and involuntary movements are produced in response to stimuli, with voluntary movements controlled by the brain and involuntary by the spinal cord. - Brief descriptions of the skeleton, muscles, and tendons in the human body.

STIMULUS AND RESPONSE

6. There are two types of stimulus:
STIMULUS AND RESPONSE
*Internal comes from inside our bodies.
*External stimuli comes from outside our
bodies.

7. STIMULUS ANDtouch, smell
RESPONSE
A stimulus is anything you see, hear,
or taste.
There are two types of stimulus:
*Internal comes from inside our bodies.
*External stimuli comes from outside our bodies.
A response is the bodies answer to a stimulus
