Tissues: Epithelial, Connective, Muscle, and Nervous

A comprehensive vocabulary review of epithelial, connective, muscle, and nervous tissues, including their classifications, cell shapes, functions, features, and specific anatomical locations based on the lecture notes.

Squamous

A flat epithelial cell shape.

Cuboidal

A square epithelial cell shape.

Columnar

A rectangular epithelial cell shape.

Transitional (Cell Shape)

An "umbrella"-shaped epithelial cell type capable of stretching across multiple layers.

Epithelial Tissue

A primary tissue type that covers and lines cavities, organs, and surfaces; functions in diffusion, protection, and absorption, and is located in the intestines, trachea, and blood vessels.

Simple Epithelium

An arrangement of epithelial tissue consisting of a single layer of cells.

Stratified Epithelium

An arrangement of epithelial tissue consisting of multiple layers of cells.

Pseudostratified Epithelium

An epithelial tissue arrangement that appears to have multiple layers but consists of a single layer of cells attached to the basement membrane.

Simple Squamous Epithelium

A single layer of flat epithelial cells; an example location is a venule.

Simple Cuboidal Epithelium

A single layer of square epithelial cells; an example location is the thyroid gland.

Simple Columnar Epithelium

A single layer of rectangular epithelial cells; an example location is the small intestine.

Pseudostratified Columnar Epithelium

An epithelial tissue that possesses cilia; an example location is the trachea.

Stratified Cuboidal Epithelium

An epithelial tissue consisting of multiple layers of square cells; an example location is a sweat gland.

Transitional Epithelium

A multi-layered tissue composed of stretchable "umbrella" cells; an example location is the urinary bladder.

Connective Tissue

A primary tissue type that connects skin to muscle, protects, transports, and stores.

Loose Connective Tissue (Areolar)

A type of loose connective tissue that holds tissue fluid and fills spaces; an example location is the mesentery.

Loose Connective Tissue (Adipose)

A type of loose connective tissue that stores energy and provides insulation; an example location is around the waist.

Loose Connective Tissue (Reticular)

A type of loose connective tissue that forms a supportive framework; an example location is a lymph node.

Dense Regular Connective Tissue

A connective tissue composed of parallel collagen fibers; an example location is a tendon.

Dense Irregular Connective Tissue

A connective tissue where collagen fibers run in different directions; located in thick skin, such as on the hands.

Elastic Connective Tissue

A connective tissue containing elastin fibers that appear black; found in ligaments and the aorta.

Hyaline Cartilage

A cartilage type found at the ends of bones and joints, the nose, and the trachea; the cells are described as looking "like eyes."

Elastic Cartilage

A type of cartilage located in the epiglottis.

Fibrocartilage

A type of cartilage that resists compression; located in the pubic symphysis.

Bone (Osseous Tissue)

A rigid connective tissue that supports and protects the body; an example location is the femur.

Spongy Bone

A form of osseous tissue located in the center of ribs.

Blood

A fluid connective tissue found inside blood vessels that transports $O_2$, nutrients, and hormones.

Muscle Tissue

A primary tissue type characterized by the ability to shorten and develop tension to produce movement.

Skeletal Muscle

A voluntary muscle tissue with visible striations responsible for body movement; located in the head and face.

Cardiac Muscle

An involuntary muscle tissue composed of striated cells with intercalated disks; located in the heart.

Smooth Muscle

An involuntary, non-striated muscle tissue found in the walls of hollow organs; an example location is the duodenum.

Neuron

A functional cell of nervous tissue; located in the brain and the cervical region of the spinal cord.
