Compound tissue - Consists of more than 2 layers and the deepest layer rest on the basement membrane. Being multilayered, it doesn’t perform the role of secretion or absorption but functions as protective layer against mechanical, chemical, thermal and osmotic stress.
Keratinised epithelial cells are basically dead skin cells. These cells are useful in the body because they protect outside bacteria and viruses from passing through into the skin. There is no real function to keratinized cells; they just protect the newer skin inside. These cells usually rub off our skin and turn into dust in our rooms.
Blood is a bodily fluid that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells lungs to be exhaled. Blood is circulated around the body through blood vessels by the pumping action of the heart. Arterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabolism produced by cells, from the tissues to the lungs to be exhaled.
Cartilage is a type of connective tissue in the body. It is made of cells called chondrocytes embedded in a matrix, strengthened with fibers of collagen and sometimes elastin, depending on the type. There are three different types: hyaline cartilage, elastic cartilage, and fibrocartilage. This tissue serves to provide structure and support to the body's other tissues without being as hard or rigid as bone. It can also provide a cushioning effect in joints.
Support: provides framework that supports and anchors all soft organs. Leg bones act as pillars to support the body trunk, and the ribs support the thorax wall. Protection: skull and vertebrae surround soft tissue of the nervous system, and the rib cage protects vital thoracic organs. Movement: skeletal muscles use the bones as levers to move the body. Storage: fat stored in the interior of the bones. Bone matrix serves as a storehouse for various minerals. Blood Cell Formation: hematopoiesis occurs within the marrow cavities of the bones.
Areolar Tissue is loose connective tissue that consists of a meshwork of collagen, elastic tissue, and reticular fibres - with many connective tissue cells in between the meshwork of fibres.
Adipose tissue is located beneath the skin and is also found around internal organs. Its main role is to store energy in the form of fat, although it also cushions and insulates the body.
The muscles are fibrous, dense tissues, whose primary function is to allow the body to move by repeated contraction and relaxation. Besides movement, the muscle is also responsible for maintaining posture, stabilizing the joints, and producing body heat through muscle function.
Muscle: None striated
Smooth muscle is an involuntary non-striated muscle. Multiunit smooth muscle tissues innervate individual cells; as such, they allow for fine control and gradual responses, much like motor unit recruitment in skeletal muscle.
Cardiac muscle (heart muscle) is a type of involuntary striated muscle found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.
A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways, but there is one key difference between neurons and other cells. Neurons are specialized to transmit information throughout the body.
Neuroglia refers to a tissue that surrounds and supports neurons in the central nervous system. This tissue forms the major part of the central nervous system. Their main function is to insulate neuron from each other.
