📝 Name of Specimen: Human Hair, c.s.
🔬 Objective/s Used: Scanner, Low-Power, High-Power, and Oil-Immersion Objectives
📚 Description: A root that is placed into the hair follicle seen under the skin’s surface plus a shaft that extends above it are the two parts that make up the human hair (KenHub, 2023). Each hair strand comprises of a cuticle, cortex, and medulla as three distinct layers. These are responsible for giving the hair its strength, color, and texture. Human hair is vital for it maintains body temperature as well as protects the skin above our head.

📝 Name of Specimen: Pig Skin, v.s.
🔬 Objective/s Used: Scanner, Low-Power, High-Power, and Oil-Immersion Objectives
📚 Description: According to Ge et al. (2012), pig skin in histology closely resembles that of a human skin, and is thus a helpful model in dermatological research. A pig skin is made up of an epidermis, dermis, and a hypodermis. More to that it is also composed of widely distributed sweat and sebaceous glands, as well as hair follicles.

📝 Name of Specimen: Frog Skin, c.s.
🔬 Objective/s Used: Scanner, Low-Power, High-Power, and Oil-Immersion Objectives
📚 Description: In an article written by Herpetologist (2022), frog’s skin is a thin, moist, delicate, slimy, and a permeable organ which allows frogs to drink, breathe, and even defend themselves from predators. Not only is the frog’s skin alluring visually, it also has significant contributions toward biological, physiological, and even medical perspectives.
