A simple cuboidal epithelium is a one-layered cell with a structure similar to a cube. These epithelial cells are used for absorption and secretion in tissues such as kidney tubules and glands. The primary function of your cuboidal epithelium is absorption and secretion due to its large surface area, which enables the substances to move freely. (Epithelium: What It Is, Function & Types, 2021)

Moreover, your nerve fibers are non-myelinated, and myelinated axons can be seen in cross-section (Peripheral Nerves | Nervous Tissue, n.d.). Non-myelinated are known to move gently or slowly, whereas your myelinated hastened actions with thick insulation. These are the ones that transmit electrical impulses, enabling cell-to-cell communication to spread throughout the entire human body. They are the carrier of action potentials in our body that allows our body to respond or react to certain stimuli.

Furthermore, blood smears are categorized as connective tissue. Red blood cells carry oxygen and nutrients widely distributed in the body. White blood cells are known to be our primary agent for protection against any foreign pathogens that enter the body. Platelets are the ones that allow our body to clot. The abovementioned are utilized to transport nutrients, hormones, and waste materials as well as protect our body.

On top of that, muscle tissue consists of skeletal muscles that are essential for contracting to create a movement. These muscles are highly utilized for maintaining body posture and body temperature through the generation of heat. It is usually found in connective tissue wrap as sarcomeres shorten when pulling the tendons to move the bones eventually creating movement to your body. (McCuller et al., 2023).
