VR Tour For Std. 10 Ch. 7. Control and Coordination
What's Included in Virtual tour of this chapter
Neurons are the cells that detect information from the environment and pass it to the brain. They also carry messages from the brain to different body parts. So, many neurons and organs get together for this work, it is called the nervous system. We will also understand reflex action. Plants exhibit two types of movements. One is the Growth-dependent movements called the Tropic Movements. And another is the growth independent movement called the Nastic Movements.

Virtual tour 1: The Human Nervous System
The nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The types of neurons are- sensory neurons, interneurons, and motor neurons.

Virtual tour 2: The reflex action
A sudden response to some environmental stimulus is known as a reflex action. The response takes place speedily at the level of the spinal cord. The reflex arc acts on an impulse even before it reaches the brain. For example, we suddenly take off our hands from the flame without thinking.

Virtual tour 3: The Human Brain
The human brain is divided into the forebrain, midbrain, and hindbrain. The forebrain is specialized in hearing, analyzing, sight, smell etcetera. The midbrain connects the forebrain and hindbrain and controls certain involuntary actions in the body. The hindbrain controls breathing, body balance, blood pressure, and vomiting.

Virtual tour 4: The endocrine glands and Hormones
Hormones are chemical substances that are secreted from endocrine glands directly in the blood. In humans, the pituitary gland, thyroid, Adrenal, Pancreas are different types of glands found in both male and female while a pair of the testis is found in male and ovaries in the female.

Virtual tour 5: Tropism in Plants
The movement of plants in response to light is called Phototropism. The roots always move in the direction of the earth’s gravity, it is called geotropism, and the movement of a plant towards the water is called hydrotropism.

Virtual tour 6: Nastism in Plants
In this virtual tour, we will understand, nastic movements of the plants. The leaves of a touch me not plant, fold up immediately when they are touched. It is called Haptonasty. Changes in the movement of the sunflower are due to the sunlight. It is called Photonasty.

Virtual tour 7: Hormones of the Plants
In this virtual tour, we will learn about Different types of hormones which are related to a different function of the plant. Hormones found in plants are Cytokinin, Ethylene, Auxin, Gibberellin, and Abscisic acid.
