form the covering of the surfaces of the body located both in internal and external parts.
Epithelial tissues
Thin, scaly-look like, flattened on the surface, fried-egg appearance with rounded nucleus.
Squamous cell
Dice shape, square-like shape with large and spherical nuclei.
Cuboidal cell
Taller rather than wide column in shape, long and rectangular shape with oblong nuclei or elongated nucleus contain goblet cells.
Columnar cell
Fine hair-like projection
Ciliated columnar cell
False stratification or appearance, free surfaces with hair-like projection, nuclei seen at different level that contain goblet cells
Pseudostratified columnar cell
made up of one layer of cells
Simple epithelium
made up of one layer of cells but of different heights, thus showing a stratified appearance.
Pseudo stratified
made up of more than two layers of cells
Stratified
kind of tissue that use to connect, bind, holds, and support one part to another part of the body. This is the most vascularized and widely distributed inside the body. It gives the body many functions like supporting the muscles to produce movement, protects the internal and delicate organs, and connects the tissues of the body.
Connective tissues
a large percentage of living cells and non-living material which is made of ground substance and fibrous structures.
Matrix
SPECIALIZED CELL: Osteocytes MATRIX: Hard or calcified SPECIFIC FUNCTION: Support, protects, provides lever, storage, hematopoiesis
Bone tissue
SPECIALIZED CELL: Red blood cell, White blood cell, Platelets MATRIX: Plasma - a fluid matrix SPECIFIC FUNCTION: Transport
Blood tissue
SPECIALIZED CELL: Chondrocytes MATRIX: Firm, Collagenous fibers SPECIFIC FUNCTION: Support, cushion properties
Hyaline cartilage
SPECIALIZED CELL: Chondrocytes MATRIX: Collagenous Fibers SPECIFIC FUNCTION: Absorb compressive shock
Fibro cartilage
SPECIALIZED CELL: Chondrocytes MATRIX: Elastic fibers SPECIFIC FUNCTION: Support the external
Elastic cartilage
SPECIALIZED CELL: fibroblasts MATRIX: Collagen structure, elastic SPECIFIC FUNCTION: Holding the organs in a particular area; between the skin and muscles
Areolar tissue
SPECIALIZED CELL: Adipocytes MATRIX: Reticular structure with collagenous fibers SPECIFIC FUNCTION: Storage of lipids for energy building; insulator
Adipose tissue
composed of muscle cells that designed for contraction and movement.
Muscle tissues
also called muscle fibers.
Muscle cells
CELL DESCRIPTION: Long cylindrical shape, Bundle forms, many nucleus ,many striations LOCATION: Skeletal muscles
Striated/voluntary/skeletal muscle cells
CELL DESCRIPTION: Short branching shape Have few striations, single nucleus /two nucleus LOCATION: Heart /cardiac muscle
Striated/involuntary/cardiac muscle cells
CELL DESCRIPTION: Spindle in shape of cells, one nucleus located at the center, absent of striations LOCATION: Visceral/smooth muscle
Non-striated/involuntary/smooth muscle cells
consists of two types of cells: conducting cells and supportive cells.
Nervous tissue
