  The body's sensory organs serve as windows for the brain, keeping it aware of what is going on in the outside environment. There are five main senses: sight, hearing, taste, smell, and touch. There are organs associated to these senses that receive information and send it to the brain, allowing the body to act on it. Sensory organs detect changes in the environment and give messages to the central nervous system. These signals are processed and integrated with other information in the CNS to produce a perception that may result in a response change. Our sensory organs allow us to perceive changes in our surroundings and alter our behaviour accordingly. Eye The eyes are complicated sensory organs. They collect information about the surroundings, which the brain interprets to create an image of what appears in the field of vision. Each eye contains a layer of receptors, a lens system that focuses light on these receptors, and a network of nerves that transmi...

  The nervous system regulates and coordinates the activity of organisms. The nervous system plays an important role in maintaining body homeostasis. In addition, it is in charge of our perceptions, behaviors, and memories, as well as controlling all voluntary motions. The nervous system is made up of two main types of cells: Neurons and Neuroglia. The nervous system's basic anatomical and functional elements are neurons, often known as nerve cells. They are designed to respond to physical and chemical stimuli, transmit nerve impulses or action potentials, and release neurotransmitters. Neuroglia, or glial cells, provide support, nourishment, and protection for neurons. Types of Nerve cells 1. Neurons: Neurons have the ability to respond to stimuli and transform them into action potentials. Most neurons consist of three parts: a Cell Body, Dendrites, and an Axon. The cell body has a nucleus surrounded by cytoplasm, which comprises typical cellular organelles such lysoso...
