The cells on the surface of stratified squamous keratinized epithelium are very flat. Not only are they flat, but they are no longer alive. They have no nucleus or organelles. They are filled with a protein called keratin, which is what makes our skin waterproof.

Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal (cube-like) cells. These cuboidal cells have large, spherical and central nuclei.

This is a cross section of a human kidney. It has simple cuboidal epithelium. The cells are roughly similar in width and length and their main function is to act as covering and secretion. Other parts with simple cuboidal epithelium include the ovary and thyroid.

Skin is very important part of our body. It functions as a protective coat. Its main function is to act as a barrier to protect the body from the outside world. It also protects our body from diseases and regulates our temperature.

Bone tissue (osseous tissue) is a hard tissue, a type of dense connective tissue. It has various functions such as storing minerals, providing internal support, protecting vital organs, enabling movement, and providing attachment sites for muscles and tendons.

The mammalian ureter contains two main cell types: a multilayered water-tight epithelium called the urothelium, surrounded by smooth muscle layers that, by generating proximal to distal peristaltic waves, pump urine from the renal pelvis toward the urinary bladder.

This picture is a striated muscle with nuclei that is under the skeletal muscle (muscle tissue). The skeletal muscle is a form of striated muscle tissue that is under voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen givers known as tendons. The skeletal muscle moves the body and is…[Read more]

Elastic cartilage is a structural cartilaginous tissue for non-load-bearing body parts, such as ears, nose, and epiglottis. In elastic cartilage, also referred to as yellow elastic cartilage, the matrix is dominated by a dense network of elastin fibres. Elastic cartilage provides support with moderate elasticity. It is found mainly in the larynx,…[Read more]

The cerebrum is a large folded mass of nervous tissue that makes up the majority of the human brain. It controls emotions, hearing, vision, personality and much more. It controls all voluntary actions. It is located in the upper part of the cranial cavity.
