Connective Tissues Flashcards
FUNCTIONS OF CONNECTIVE TISSUES:
- Protection and Connection between different tissues
- Storage, Support and transport of nutrients and waste
LOOSE CONNECTIVE TISSUES
AREOLAR TISSUES
ADIPOSE TISSUES
RETICULAR TISSUES
LOOSE CONNECTIVE TISSUES
- A fine network of fibers (mostly collagen fibers with a few elastic fibers) with spaces between the fibers; fibroblasts, macrophages, and lymphocytes are located in the spaces.
AREOLAR CONNECTIVE TISSUE
LOOSE CONNECTIVE TISSUES
FUNCTION
- Loose packing, support and nourishment for the structures with which it is associated.
AREOLAR CONNECTIVE TISSUE
LOOSE CONNECTIVE TISSUES
LOCATION
- Widely distributed throughout the body; substance on which epithelial basement membranes rest; packing between glands, muscles, and nerves; attaches the skin to underlying tissues.
AREOLAR CONNECTIVE TISSUES
LOOSE CONNECTIVE TISSUES
- Little extracellular matrix surrounding cells; the adipocytes, or fat cells, are so full of lipid that the cytoplasm is pushed to the periphery of the cell
ADIPOSE TISSUE
LOOSE CONNECTIVE TISSUES
FUNCTION
- Packing material, thermal insulator, energy storage, and protection of organs against injury from being bumped or jarred.
ADIPOSE TISSUE
LOOSE CONNECTIVE TISSUES
LOCATION
- Predominantly in subcutaneous areas, mesenteries, renal pelves, around kidneys, attached to the surface of the colon, mammary glands, and in loose connective tissue that penetrates into spaces and crevices.
ADIPOSE TISSUE
LOOSE CONNECTIVE TISSUES
- Fine network of reticular fibers irregularly arranged
RETICULAR TISSUES
LOOSE CONNECTIVE TISSUES
FUNCTION
- Provides a superstructure for lymphatic and hemopoietic tissues.
RETICULAR TISSUE
LOOSE CONNECTIVE TISSUES
LOCATION
- Within the lymph noses, spleen, bone marrow
RETICULAR TISSUE
DENSE CONNECTIVE TISSUES
REGULAR COLLAGENOUS
REGULAR ELASTIC
DENSE CONNECTIVE TISSUES
- Matrix composed of collagen fibers running in somewhat the same direction in tendons and ligaments; collagen fibers run in several directions in the dermis of the skin and in organ capsules.
DENSE REGULAR COLLAGENOUS CONNECTIVE TISSUE
DENSE CONNECTIVE TISSUES
FUNCTION
- Withstand great pulling forces exerted in the direction of fiber orientation due to great tensile strength and stretch resistance
DENSE REGULAR COLLAGENOUS CONNECTIVE TISSUE
DENSE CONNECTIVE TISSUES
LOCATION
- Tendons (attach muscle to bone) and ligaments (attach bones to each other); also found in the dermis of the skin, organ capsules, and the outer layer of many blood vessels.
DENSE REGULAR COLLAGENOUS CONNECTIVE TISSUE
DENSE CONNECTIVE TISSUES
- Matrix composed of collagen fibers and elastin fibers running in somewhat the same direction in elastic ligaments; fibers run in connective tissues of blood vessel walls
DENSE REGULAR ELASTIC CONNECTIVE TISSUE
DENSE CONNECTIVE TISSUES
FUNCTION
- Capable of stretching and recoiling like a rubber band with strength in the direction of fiber orientation.
DENSE REGULAR ELASTIC CONNECTIVE TISSUE
DENSE CONNECTIVE TISSUES
LOCATION
- Elastic ligaments between the vertebrae and along the dorsal aspect of the nectar (nucha) and in the vocal cords; also found in elastic connective tissue of blood vessel walls.
DENSE REGULAR ELASTIC CONNECTIVE TISSUE
SKELETAL CONNECTIVE TISSUE
HYALINE CARTILAGE
FIBROCARTILAGE
ELASTIC CARTILAGE
BONES
SKELETAL CONNECTIVE TISSUE
- Collagen fibers are small and evenly dispersed in the matrix, making the matrix appear transparent; the chondrocytes are found in spaces, or lacunae, within the firm but flexible matrix
HYALINE CARTILAGE
SKELETAL CONNECTIVE TISSUE
FUNCTION
- Allows growth of long bones; provides rigidity with some flexibility in the trachea, bronchi, ribs, and nose; forms strong, smooth, yet somewhat flexible articulating surfaces, forms the embryonic skeleton
HYALINE CARTILAGE
SKELETAL CONNECTIVE TISSUE
LOCATION
- Growing long bones, cartilage rings of the respiratory system, costal cartilage of ribs, nasal cartilages, articulating surface of bones, and the embryonic skeleton
HYALINE CARTILAGE
SKELETAL CONNECTIVE TISSUE
- Collagen fibers similar to those in hyaline cartilage; the fibers are more numerous than in other cartilages and are arranged in thick bundles
FIBROCARTILAGE
SKELETAL CONNECTIVE TISSUE
FUNCTION
- Somewhat flexible and capable of withstanding considerable pressure; connects structures subjected to great pressure
FIBROCARTILAGE
SKELETAL CONNECTIVE TISSUE
LOCATION
- Intervertebral disks, pubic symphysis. and articular disks (eg. knees and temporomandibular (jaw) joints)
FIBROCARTILAGE
SKELETAL CONNECTIVE TISSUE
- Similar to hyaline cartilage, but matrix also contains elastin fibers
ELASTIC CARTILAGE
SKELETAL CONNECTIVE TISSUE
FUNCTION
- Provides rigidity with even more flexibility than hyaline cartilage because elastic fibers return to their original shape after being stretched
ELASTIC CARTILAGE
SKELETAL CONNECTIVE TISSUE
LOCATION
- External ears, epiglottis, and auditory tubes
ELASTIC CARTILAGE
SKELETAL CONNECTIVE TISSUE
- Hard, bony matrix predominates; many osteocytes (not seen in this bone preparation) are located within lacunae; the matrix is organized into layers called Lamellae
SUPPORTING CONNECTIVE TISSUE: BONE
SKELETAL CONNECTIVE TISSUE
FUNCTION
- Provides great strength and support and protects internal organs, such as the brain; bone also provides attachment sites for muscles and ligaments; the joints of bones allow movements
SUPPORTING CONNECTIVE TISSUE: BONE
SKELETAL CONNECTIVE TISSUE
LOCATION
- All bones of the body
SUPPORTING CONNECTIVE TISSUE: BONE
CARDIOVASCULAR TISSUE
- Blood cells and a fluid matrix
FLUID CONNECTIVE TISSUE: BLOOD
MUSCULAR TISSUE
SKELETAL MUSCLE
CARDIAC MUSCLE
SMOOTH MUSCLE
MUSCULAR TISSUE
- Appear striated (banded); cells are large, long, and cylindrical with many nuclei
SKELETAL MUSCLE
MUSCULAR TISSUE
FUNCTION
- Movement of the body; under voluntary control
SKELETAL MUSCLE
MUSCULAR TISSUE
LOCATION
- Attached to bone or other connective tissue
SKELETAL MUSCLE
MUSCULAR TISSUE
- Cylindrical and striated and have a single nucleus; they are branched and connected to one another by intercalated disks, which contain gap junctions
CARDIAC MUSCLE
MUSCULAR TISSUE
FUNCTION
- Pumps the blood; under involuntary (unconscious) control
CARDIAC MUSCLE
MUSCULAR TISSUE
LOCATION
- In the heart
CARDIAC MUSCLE
MUSCULAR TISSUE
- Tapered at each end, are not striated, and have a single nucleus
SMOOTH MUSCLE
MUSCULAR TISSUE
FUNCTION
- Regulates the size of organs, forces fluid through tubes, controls the amount of light entering the eye and produces ‘’goose bumps” in the skin, under involuntary (unconscious) control
SMOOTH MUSCLE
MUSCULAR TISSUE
LOCATION
- In hollow organs, such as the stomach and intestines; skin and eyes.
SMOOTH MUSCLE
NERVOUS TISSUE
- A neurons consists of dendrites, a cell body, and a long axon; neurolgia, support cells, surround the neurons
NERVOUS TISSUE: NEURONS
NERVOUS TISSUE
FUNCTION
- Neurons transmits information in the form of action potentials, store information, and integrate and evaluate data: neuroglia support, protect and form specialized sheaths around axons
NERVOUS TISSUE: NEURONS
NERVOUS TISSUE
LOCATION
- In the brain, spinal cord, and ganglia
NERVOUS TISSUE: NEURONS
