Biol 123 Lecture: Cytoskeleton and Tissue Function

These flashcards cover vocabulary terms related to tissues and the cytoskeleton, essential for understanding cellular structure and function.

Tissue

A collection of cells that work together to perform a specific function.

Epithelial Tissue

A type of tissue that covers the outside of the body and lines organs and cavities.

Connective Tissue

Tissue characterized by few cells and substantial amounts of extracellular matrix.

Microfilaments

The thinnest cytoskeletal type, composed of actin monomers, involved in cell shape and movement.

Microtubules

Cylindrical tubes formed from tubulin dimers, providing structural support and aiding in intracellular transport.

Intermediate Filaments

Fibrous proteins providing tensile strength, specific to animal cells, with no movement or transport functions.

Motor Protein

Proteins that move along cytoskeletal fibers, driven by ATP hydrolysis, enabling cellular movement and transport.

Basal Lamina

A layer of extracellular matrix to which epithelial tissues are attached.

Epidermis

The outer layer of skin, comprised mainly of epithelial tissue.

Dermis

The inner layer of skin, a type of connective tissue that supports the epidermis with nutrients.
