Tissue

• Epithelial tissue covers the surfaces of the body, including the skin and the lining of the digestive tract.
• Connective tissues provide support and binding together of body parts. They include blood, bone, cartilage, tendons and ligaments.
• Connective tissue includes various types such as bone, cartilage, tendons, ligaments, and adipose tissue.
• Nervous tissue is responsible for transmitting electrical signals and coordinating body functions.
• The epithelium consists of cells arranged into sheets or layers called epithelia.
• Muscle tissues enable movement. They consist of striated and smooth muscles.
• Connective tissue provides support to other tissues and organs, such as bone and cartilage.
• Epithelial tissue is the most abundant type of tissue, covering all surfaces that are exposed to the external environment.
• There are four types of epithelia based on their shape: simple squamous (single layer), simple cuboidal (cubical), simple columnar (tall), and stratified (multiple layers).
• Epithelial tissues line the outer surfaces of organs and blood vessels as well as the inner surfaces of cavities in many internal organs.
• Muscle tissue is responsible for movement and contraction, found in skeletal muscles and heart muscle.
• Muscle tissue contracts to produce movement or maintain posture.
• Nervous tissue consists of neurons and neuroglia cells, transmitting electrical impulses throughout the body.
• Striated muscle is found in skeletal muscles that attach to bones.
• Smooth muscle tissue is found in the walls of hollow organs and blood vessels.
• Cardiac muscle tissue is only present in the heart and has unique properties such as branching fibers, intercalated discs, and involuntary contractions.
• Blood is composed of plasma, red blood cells, white blood cells, and platelets, transporting oxygen, nutrients, hormones, and waste products throughout the body.
• Cardiac muscle is found only in the heart.
• The nervous system consists of neurons and neuroglia cells.
• Bone tissue forms the skeleton and provides structural support, protection, and storage of minerals.
• Simple Columnar Epithelium has tall cells with one nucleus per cell.
• Simple Columnar Epithelium has tall rectangular cells with one nucleus per cell.
• Connective tissue provides support, protection, and connectivity between structures, including bone, cartilage, adipose, areolar, reticular, dense regular, and dense irregular.
• Blood is a fluid connective tissue composed of plasma and formed elements such as red blood cells, white blood cells, and platelets.
• Bone tissue provides structure and support to the body, with different types including compact bone (cortical) and spongy bone (trabecular).
• Smooth Muscle is involuntary and found in walls of hollow organs such as stomach, intestines, uterus, blood vessels, and bladder.
• Cartilage tissue is avascular and aneural, providing flexibility and cushioning at joints and protecting organs.
• Adipose tissue stores energy in the form of fat droplets within its cells.
• Areolar tissue fills spaces between other tissues and contains fibroblasts that produce collagenous and elastic fibers.
