Good day, everyone!! Attached below is a picture of my Activity 4 (Integumentary Tissues). This also includes a brief description:

Human hair: Hair grows from tiny pockets in your skin called follicles. It’s made of a tough protein called keratin and helps keep you warm, protects your scalp from the sun, and can even sense touch (The Editors of Encyclopaedia Britannica, 1998)
Human scalp: The scalp is the skin on your head where your hair grows. It’s thicker than most skin on your body and has more oil glands to keep your hair healthy (WebMD, 2023).
Human palmar skin: The palmar skin is the skin on the palms of your hands. It’s thicker and tougher than most skin because it helps you grip things. It also has special sweat glands that help you cool down and improve your grip (Montagna & Ebling, 2024)
Human palmar skin section: A section of human palmar skin, when viewed under a microscope, reveals several layers. The topmost layer is made of tough, dead skin cells for protection. Below that are living cells that constantly renew the outer layer. Deeper still are blood vessels, nerves, and special sweat glands. These glands produce sweat to help cool your body and improve your grip (Palmar and Plantar Keratosis | Skin Disease, n.d.)
