Complete Tissues & Integumentary Study Guide

Vocabulary flashcards covering essential topics in tissues and the integumentary system.

Location of epithelium

Lines internal and external body surfaces.

Characteristics of epithelium

Avascular, high regeneration, cellularity, polarity.

First name in epithelium naming

Describes the number of layers: simple (1), stratified (many), pseudostratified (appears many).

Second name in epithelium naming

Describes the shape: squamous (flat), cuboidal (cube), columnar (tall).

Simple squamous epithelium

Found in alveoli and involved in diffusion.

Simple cuboidal epithelium

Found in kidney tubules and involved in absorption/secretion.

Simple columnar epithelium

Found in the digestive tract and involved in absorption/secretion.

Stratified squamous epithelium

Found in skin and provides protection.

Pseudostratified ciliated columnar epithelium

Found in the respiratory tract and involved in mucus movement.

Transitional epithelium

Found in the bladder and allows stretching.

Components of connective tissue

Cells, protein fibers, ground substance.

Types of connective tissue fibers

Collagen (strength), elastic (stretch), reticular (support).

Areolar tissue

Supports epithelium.

Adipose tissue

Involved in fat storage.

Dense regular connective tissue

Found in tendons/ligaments providing unidirectional strength.

Dense irregular connective tissue

Provides multidirectional strength.

Bone

Provides structure and protection.

Types of cartilage

Hyaline (support), fibrocartilage (shock), elastic (flexible).

Skeletal muscle

Striated, voluntary muscle involved in movement.

Smooth muscle

Non-striated, involuntary muscle found in organs.

Cardiac muscle

Striated, involuntary muscle in the heart with intercalated discs.

Function of neurons

Communication in the nervous system.

Function of neuroglia

Support cells in the nervous system.

Functions of skin

Protection, temperature regulation, sensation.

Stratum corneum

Outer layer of skin, made of dead cells.

Stratum lucidum

Layer found only in thick skin.

Stratum granulosum

A layer of the epidermis.

Stratum spinosum

A layer of the epidermis.

Stratum basale

Bottom layer of the epidermis where cell division occurs.

Keratinocytes

Main cells of the epidermis.

Melanocytes

Cells that produce melanin in the skin.

Langerhans cells

Cells involved in immune response in the skin.

Merkel cells

Cells that detect touch in the skin.

Sebaceous glands

Oil-producing glands in the skin.

Sudoriferous glands

Sweat glands in the skin.

Ceruminous glands

Glands that produce earwax.
