Answer:

1)answer:A reflex action is an involuntary action which is a rapid and automatic response to stimuli. Walking is a voluntary action, which requires our thinking and is within our control.

2)answer: Transmission of nerve impulses between two neurons takes place through the synapse. The axon terminal of a neuron releases specilized chemicals called neurotransmitters. These chemicals travel through the synapse and reach the dendrites of the next neuron. The nerve impulses travel along with the neurotransmitters.

3) ANSWER: The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. The brain is made up of many specialized areas that work together: The cortex is the outermost layer of brain cells.

4) ANSWER: The endocrine system is made up of a network of glands. These glands secrete hormones to regulate many bodily functions, including growth and metabolism.

Hypothalamus.

Pineal Gland.

Answer:

1. reflex action:

reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus.

Reflex Arc:

A reflex action is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.
