Animal Tissues Flashcards
It is a group of cells that have similar structure and that function together as a unit.
Tissue
A nonliving material that fills the spaces between the cells
Intercellular matrix
Types of Animal Tissues
- Epithelial tissue
- Connective tissue
- Muscle Tissue
- Nervous Tissue
Are closely packed cell sheets that cover the body’s surface and line internal organs and cavities, providing protection and facilitating exchanges.
Epethilial Tissues
A thin, specialized extracellular matrices surrounding most tissues in all metazoans
Basement membrane / basal lamina
Simple layer of Epithelial Tissue cell shapes
- Pseudostratified
- Squamous
- Cuboidal
- Columnar
If Pseudostratified forms a cilia
Ciliated and Non-ciliated
Compound layer of Epithelial Tissue cell shapes
- Stratified
- Transitional
Compound Stratified Epithelial cell shapes
- Stratified Squamous
- Stratified Cuboidal
- Stratified Columnar
If Stratified Squamous contains keratin
Keratinized and Non-keratinized
Squamous example
Esophagus
Cuboidal example
Kidney
Columnar example
Stomach
Simple layer cell example
Lung alveoli
Stratified or multiple layered cell example
Epidermis
Pseudostratified or one layer of cell in a multilayered appearance
Trachea
A serous membrane that surrounds and protects the heart
Pericardium
A serous membranes that enclose the lungs and line the thoracic cavity
Pleura
A serous membrane that lines the abdominal cavity and covers the abdominal organs
Peritoneum
Keratinized layer is also called as
Stratum Corneum
3 main component of Connective tissues derived from embryonic mesenchyme
- Cells (Fibroblast, Osteoblast, Chondroblast)
- Proteinaceous fibers (Collagen fibers, Elastic fibers)
- Matrix/ground substance (solid, soft, or liquid)
Collagen fibers arranged in a parallel or wave-like fashion. Examples are tendons and ligaments
Dense Regular
Collagen fibers arranged randomly. Examples are periosteum, perichondrium
Dense Irregular
Gives structure to organs and muscles
Reticular connective tissue
Types of cells dispersed among many types of fibers in a semifluid matrix
Areolar connective tissue
- Serves as stored energy
- Acts as cushion for many internal organs
Adipose Tissue
Locations of Adipose Tissue
- Subcutaneous layer deep to skin
- Yellow marrow of the long bones
- Around the heart
- Inside the eye-socket, posterior to the eyeball
- Around the kidneys
- Paddings around the joints
- Solid yet pliable to a certain extent
- Scattered lacunae
Cartilage
What are the types of Cartilage
- Hyaline Cartilage
- Fibro Cartilage
- Elastic Cartilage
- Consists of chondrocytes
scattered among clearly visible dense bundles of collagen fibers. - Strongest among the cartilages
Fibro Cartilage
Its function is to resist strong forces of compression and tension
Fibro Cartilage
- Very flexible, provides support and
maintain shape - Usually forms much of the fetal skeleton
- Eases joint movement
- Makes up the external ear and
epiglottis.
Elastic Cartilage
Provides smooth surface for gliding action and joints
Hyaline Cartilage
Types of Bones
- Cancellous Bone
- Compact Bone
Parts of Bone Tissue
- Haversian canal
- Lacunae
- Osteocyte
- Canaliculi
- Lamella
Components of Blood/Vascular Tissue
Plasma and Blood Corpuscles
Function of white blood cells
Protection against bacteria, viruses and parasites
Muscles controlled by the will
Voluntary Muscles
Muscles that cannot be controlled by the will
Involuntary Muscles
Example of voluntary muscle
Skeletal muscles
Example of involuntary muscle
Smooth muscle and Cardiac Muscle
Forms a communication network
Nervous Tissue
