The uppermost layer of skin is the the stratum corneum.
squamouslike
Stratified squamous epithelia are named based on the characteristics of the uppermost layer of cells. If the top layer is composed of squamous (flat) cells, the epithelium is referred to as "stratified squamous epithelium." This naming convention helps to identify the type of epithelium based on its surface features and function.
The uppermost layer of skin is called the epidermis. It is primarily composed of keratinized stratified squamous epithelium, consisting mainly of keratinocytes that produce keratin, a protein that helps protect the skin. The epidermis also contains melanocytes, which produce melanin for pigmentation, and Langerhans cells, which are involved in immune response. This layer serves as a barrier to environmental damage and helps prevent water loss.
Capillaries are the smallest blood vessels in the body, consisting of a single layer of endothelial cells. They are where oxygen and nutrients are exchanged with tissues.
The uppermost layer of the packed cell column is formed by red blood cells, also known as erythrocytes. Red blood cells are the most abundant type of blood cell and are responsible for carrying oxygen from the lungs to the rest of the body. They are disc-shaped cells that lack a nucleus and contain hemoglobin, a protein that binds to oxygen.
The uppermost layer of the Earth is called the crust. It is the thinnest and outermost layer of the Earth, consisting of solid rock and soil. The crust is divided into several tectonic plates that float on the semi-fluid mantle beneath them.
The uppermost layer of dirt is typically called topsoil. It is the outermost layer of soil that is rich in organic matter and nutrients, making it ideal for plant growth.

It is called 'topsoil'

spongy layer
The outermost layer of the epidermis consisting of dead cells is called the stratum corneum. These dead cells are continuously shed and replaced by new cells from the underlying layers of the epidermis.
