• "eurons have the special ability to carry signals or impulses.• #he nerve impulse is an electrochemical signal moving along a neuron.
• #he space between neurons is called synapse.
• #he stimulus is any factor in the environment that inuences behaviour.
• $ response is a reaction to a condition or stimulus.
• $n organism must be able to respond to a stimulus in order to survive.
• %eceptor such as an organ perceives a stimulus, the impulse is sent to the
brain by the sensory neurons, which then transmit information from one nerve
cell to another.

• $s the message reaches the brain, it processes the information and commands
an e&ectors such as a muscle or an organ to respond.
• 'essage coming from the brain sent through the motor neurons.

#he ndocrine ystem is composed of glands that secrete di&erent types of
hormones that a&ect almost every cell, organ, and function of our body. t is essentialin regulating growth and development, metabolism, as well as reproductive
processes and mood. ENDOCRINE 4LANDS AND THEIR HORMONES
PITUITARY
/stimulates growth, and controls the functions of the other glands
THYROID
/regulates body metabolism, and causes storage of calcium in bones
PARATHYROID

http://slidepdf.com/reader/full/module-1-team-dna 3/5
/controls the calcium levels in your body, and normalizes bone growth
THYMUS
/enables the body to produce certain antibodies
ADRENAL
/prepares the body for action, controls the heart rate and breathing in times of
emergency
PANCREAS
/regulates blood sugar levelsREPRODUCTIVE
(TESTES) controls maturation and males characteristics
(OVARIES) inuence female traits, and support reproductive function

is any self+regulating process by which biological systems tend tomaintain stability while adusting to conditions that are optimal for
survival. f homeostasis is successful, life continues- if unsuccessful, disaster or death ensues. #he stability attained is
actually a dynamic euilibrium, in which continuous change occursyet relatively uniform conditions prevail.
