What is the sequence of the nervous response process starting from a stimulus?

Stimulus --> Receptor --> Coordinator --> Effector --> Response.

What defines a Stimulus in the context of the nervous system?

A change in the environment, imbalance, or an evasion from an opponent.

What are examples of receptors in the nervous system?

Specialised receptor cells such as those in the eyes and ears.

What is the main role of the Coordinator in the nervous system?

To process information using the brain or spinal cord.

What are Effectors in the nervous system?

Muscles or glands that carry out the response.

What are the two main parts of the Nervous System?

Central Nervous System (CNS) and Peripheral Nervous System (PNS).

What does the Central Nervous System consist of?

The brain and spinal cord.

What is the primary function of the Central Nervous System?

Processing and integrating information.

What is the function of the Peripheral Nervous System?

To connect the CNS to the rest of the body through nerves.

What are Efferent pathways responsible for in the nervous system?

Carrying signals from the CNS to the effectors.

What do sensory nerves do in the Peripheral Nervous System?

Inform the CNS about the environment inside and outside the body.

What is the Motor neurone system's function?

Controls movement and muscle contraction.

What is the difference between the somatic system and the autonomic system?

The somatic system controls voluntary movements, while the autonomic system regulates involuntary functions.

What are the two divisions of the autonomic system?

Sympathetic system and parasympathetic system.

What is the role of the Sympathetic system?

To activate the fight or flight response and stimulate an increase in response.

What does the Parasympathetic system do?

Promotes rest functions and stimulates a decrease in response.
