Pbiology exam tomorrow with Mr. gorey?
Nervous tissue is derived from the ectoderm germ layer during embryonic development.
The fatty layer of tissue that gives many nerves a whitish color is called myelin. Myelin is produced by specialized cells called Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system. It acts as an insulating layer around nerve fibers, allowing for faster conduction of nerve impulses.
In the skin, the fat layer is called the subcutaneous tissue or adipose tissue.
The layer of living skin you are referring to is called the dermis. It is composed of all major tissue types, including epithelial tissue, connective tissue, muscle tissue, and nervous tissue. The dermis provides structural support, contains blood vessels, nerve endings, and glands, and is responsible for giving skin its strength and elasticity.
The main types of primary tissues in the human body are epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue forms the outer layer of the skin and lines the body's cavities. Connective tissue supports and binds other tissues together. Muscle tissue is responsible for movement, and nervous tissue allows for communication through electrical signals.

A nerve cell is actually called a neuron. It is the structural and functional unit of the nervous system. It can also be called a nerve fiber.
The embryo layer that forms the skin and nervous tissue is the ectoderm. It gives rise to the epidermis of the skin, hair, nails, and the nervous system including the brain and spinal cord. The ectoderm is one of the three primary germ layers that develop during gastrulation in embryogenesis.

Epithelial tissue
The thin layer of tissue that covers the body of a mollusk is called the "mantle."
All nervous tissue arise from ectoderm. Whether central or peripheral. It is anatomical division. Functionally all nervous cells are connected to each other.
Tissue
A nerve is an enclosed, cable-like bundle of axons in the peripheral nervous system. Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium.
The main types of primary tissues in the human body are epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue forms the outer layer of the skin and lines the body's cavities. Connective tissue supports and binds other tissues together. Muscle tissue is responsible for movement, and nervous tissue allows for communication through electrical signals.
