Frequently Asked Questions

Coordination refers to the process by which different organs and systems of living organisms work together harmoniously to respond to stimuli and maintain homeostasis.

The nervous system and endocrine (hormonal) system control and coordinate various functions in animals.

The neuron is the structural and functional unit of the nervous system.

A neuron consists of the cell body, axon, and dendrites.

The human brain includes the forebrain, midbrain, and hindbrain.

The cerebrum controls voluntary actions, thinking, memory, reasoning, and intelligence.

A reflex action is a quick, automatic response to a stimulus, often controlled by the spinal cord.

The spinal cord transmits signals between the brain and the rest of the body and coordinates reflexes.

Sensory neurons carry information from sense organs to the central nervous system.

Motor neurons carry signals from the central nervous system to muscles or glands.

The endocrine system is a system of glands that secrete hormones to regulate various body functions.

Hormones are chemical messengers produced by endocrine glands that travel through blood to target organs.

The pituitary gland is known as the master gland because it controls other endocrine glands.

Important hormones include insulin, adrenaline, thyroxine, growth hormone, and sex hormones.

Phototropism is the movement or growth of a plant in response to light.
