Pictures and structures and functions of the sense organs
1. Eyes: The eyes are the sense organs responsible for vision. They detect light and convert it into electrical signals that are sent to the brain for interpretation. The eye is made up of various structures including the cornea, pupil, iris, lens, and retina.
2. Ears: The ears are the sense organs responsible for hearing and maintaining balance. The ear is divided into three main parts - the outer ear, middle ear, and inner ear. The outer ear collects sound waves and directs them to the middle ear, where they are amplified and transmitted to the inner ear. The inner ear contains the cochlea, which converts sound waves into electrical signals that are sent to the brain.
3. Nose: The nose is the sense organ responsible for the sense of smell. It contains olfactory receptors that detect chemical molecules in the air and send signals to the brain for interpretation. The nose also plays a role in taste, as it is connected to the mouth and helps detect flavors.
4. Tongue: The tongue is the sense organ responsible for the sense of taste. It contains taste buds that detect different flavors - sweet, salty, sour, bitter, and umami. The tongue also plays a role in speech and swallowing.
5. Skin: The skin is the largest sense organ in the body and is responsible for the sense of touch, temperature, and pain. It contains various receptors that detect different stimuli and send signals to the brain for interpretation. The skin also plays a role in regulating body temperature and protecting the body from harmful external factors.
