What are the four basic elements involved in the Interaction Function?
stimuli, receptors, coordination centers, and effectors
What is the function of Divergent Circuits?
carries nerve impulses from one place to several organs
What two systems are Effectors?
the endocrine system and the locomotor system
What makes up the central nervous system?
the Brain and the Spinal Cord
What is this an example of: in cold weather, the nervous system and endocrine systems work together to keep the body's internal temperature at 37 degrees.
Homeostasis
What is the function of Convergent Circuits?
carries impulses from several places to one organ
What is an Axon?
a long nerve fibre that carries electrical messages from the cell body and sends it to other cells
What are stimuli?
any changes in the environment that are detected by an organism
What are the three groups that neurons can be put into?
Sensory neurons, Motor neurons, and Interneurons
What is the function of Grey Matter?
processes information in the brain
what are receptors?
Located in the sense organs that detect stimuli and send information to the nervous system
what does the endocrine system do?
produce hormones
What is homeostasis?
the body's ability to maintain a stable internal environment when it detects changes in the external environment
What is Negative Feedback?
A process that occurs when an organism reacts to stimuli by slowing down or stopping a process that's happening
What does the cell body contain?
the nucleus and cytoplasmic organelles
White Matter and Grey Matter make up what 2 parts of the central nervous system?
the brain and the spinal cord
what does the locomotor system produce?
movement
What are Dendrites?
short nerve fibers that carry information from other neurons to the cell body
True or False: the action of the Nervous System is long-lasting
false, it is short-lasting
what are effectors?
muscles and glands that receive the response and react to the stimuli
What 2 systems is the nervous system divided into?
central nervous system and peripheral nervous system
What is the function of interneurons?
carry information between motor and sensory neurons
What are coordination centers?
Where the nervous system receives the information and sends a response to the effectors
What is the function of Sensory Neurons?
carry information from the senses to the brain
What is the function of motor neurons?
carry information from the brain to muscles or glands
What is the function of the cell body?
The cell body receives information, it contains the nucleus and cytoplasmic organelles
What part of the neuron structure is a long nerve fibre that carries electrical messages from the cell body and sends it to other cells?
Axon
What are reflexes?
automatic actions that the body does in response to stimuli
When neurons connect to each other, what is it called?
a circuit
What is another name for the cell body?
Soma
