Study Notes
Sense Organs
- Chameleons can move their eyes independently, allowing them to see in two directions simultaneously.
- Human nose contains nerve endings that send messages about chemical substances, enabling the sense of smell.
- The human ear consists of three parts: outer ear (visible portion), middle ear (contains ear drum and ossicles), and inner ear (responsible for hearing and balance).
- Different animals have varied external ear shapes, which aid in sound direction.
- The human tongue possesses approximately 9,000 taste buds, sensitive to four tastes: sweet, sour, salty, and bitter; pigs have 15,000 and rabbits have 17,000.
- Skin is the largest sense organ, providing protection and sensations of pain, touch, pressure, heat, and cold.
Joints
- Gliding joints are found in wrists, ankles, and between vertebrae, allowing for flexibility and movement in multiple directions.
- Understanding body part movements can help identify the type of joint involved in each action.
Sensory Processing
- Humans rely on five sensory organs: nose, eyes, ears, tongue, and skin to gather information, which is sent to the brain for processing.
- Dysfunction in any sense organ impacts one's ability to smell, see, hear, taste, or feel.
Eyes Anatomy
- Eyeballs are housed in bony sockets and protected by eyelids and eyelashes from debris.
- The iris is the colored part of the eye, while the pupil allows light to enter, and the retina is where images are formed.
Plant Nutrition
- Plants, like humans and animals, require energy to grow, repair, and reproduce, obtained through food.
- Green leaves act as food factories through a process called photosynthesis, which synthesizes food using carbon dioxide and water in the presence of light (photo means ‘light’ and synthesis means ‘putting together’).
