Nerves that detect deep pressure are called Pacinian corpuscles.
Pacinian corpuscles are microscopic onion-shaped nerve structures that are situated in the dermis and hypodermis. Pacinian corpuscles detect deep pressure and vibration. This nerve has a myelinated nerve ending in the middle of its structure and the external layer contains flattened cells, a lymph-like fluid and collagen fibers. The structure of pacinian corpuscles provides a fast response and rapid recovery by transmitting fast events. This make them sensitive to pressure and vibration.
Answer:
Villi
Explanation:
In the small intestine, villi are found present. These villi which appear like a finger-like tissue structure are about 0.5–1.6mm in length in human beings.They have mucosal cells that help in absorption of nutrients. A villus has several microvilli, which increases the surface area of the intestinal wall for faster absorption of nutrients.
Answer:
Blood
Explanation:
Connective tissue consists of extracellular matrix and cells. The main function of connective tissue is to bind the other tissues together, provide them support and strength. Blood is one of the liquid connective tissue that does not perform such functions. The presence of liquid extracellular matrix (plasma) and formed elements (blood cells) makes it a connective tissue. It serves in the transport of nutrients, gases, wastes, hormones, etc. It also takes part in immune responses but does not strength or support other body tissues.
June 21st represents the sun in the sky at noon for the northern hemisphere.
Explanation:
The summer is hotter because the sun's part is higher in the sky. This reason makes the days longer and makes summer sun more intense.
The summer solstice for northern hemisphere occurs in june 21. On this day the sun's position at noon is higher in altitude of the year.
In the summer season , The north pole is tilted towards the sun and this causes the sun's part to be higher in the sky causing the northern hemisphere to receive more light and heat.
