: Forms coverings and linings. It is classified by cell shape (squamous, cuboidal, columnar) and number of layers— simple (single layer) or stratified (multiple layers).

: Specialized for communication via electrical signals. 2. Specialized Organ Layers

: The outermost epithelial layer, itself made of up to five sub-layers (from superficial to deep: stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale ). tissue layer

Several major organ systems are characterized by specific tissue layer arrangements: The skin consists of three primary layers:

: Binds, supports, and protects. Examples include bone, blood, and the dermis layer of the skin. : Forms coverings and linings

: Contracts to provide movement. Skeletal muscles are organized into layers of connective tissue: epimysium (outer), perimysium (middle), and endomysium (inner).

At the cellular level, tissues are organized into four primary types that form layers throughout the body: Examples include bone, blood, and the dermis layer

: Mainly composed of adipose (fat) and loose connective tissue that anchors skin to underlying structures. Anatomy & Physiology Tissue Study Guide for Exam Success
