This document describes the key characteristics of 14 different types of tissues in the human body: 1) Dense irregular connective tissue forms strong layers like the dermis and organ capsules. Its fibers intertwine randomly. 2) Bone tissue contains mineral salts and is highly specialized, housing osteocytes. 3) Hyaline cartilage is prevalent and found in respiratory tubes and joint surfaces. It provides concise summaries of the key tissues in the human body in a clear and organized manner.
What Can I See?
- 1. What Can I See? Taylor Douglas, Ashley Lanum, Ashley Bookston, Jessica Cisneros, Aldana Alarcon, and Syeda Syyara
- 2. Dense Irregular Fibrous • in the dense irregular fibrous tissue the bundles of fiber aren’t I parallel rows • the fibers intertwine to form a thick mat of strong connective tissue • it can withstand stresses applied from any direction • it forms the strong inner skin layer called the dermis • it also forms the outer capsule of such as the kidney and the spleen
- 3. Bone Tissue • it is one of the most highly specialized tissues • the mature bone cells are called osteocytes; they embedded in a unique matrix material containing both organic collagen material and mineral salts • the inorganic bone salt is responsible for the hardness of the bone
- 4. Hyaline Cartilage • this is the most prevalent type of cartilage • it is found in the support rings in the respiratory tubes • also covering the ends of the bones that articulate at joints
- 5. Fibrocartilage • the strongest, most durable cartilage • fibrocartilage disks serve as shock absorbers • the matrix is rigid and is packed with strong white collagen fibers
- 6. Simple Squamous • One layer of flat, scale-like cells • Easily permeable • Found in alveoli
- 7. Stratified Squamous • Multiple layers of cells • Flattened squamous cells at outer surface • Contain Keratin which contributes to the protective qualities ©7
- 8. Transitional Tissue • Contains cells that are flattened • Contains cells that are cuboidal • Lines urinary passages ©8
- 9. Simple Columnar • Lines stomach, intestine, uterus • Single layer of cells • Goblet cells, cilia, and microvilli ©9
- 10. Stratified Columnar • Lining air passages • Single layer of irregularly shaped cells • Not all cells reach top and bottom ©10
- 11. Pseudostratified Lines the air passages of the respiratory system (1) page 129 Only a single layer of irregularly shaped columnar cells touches the basement membrane (1) page 129 Mucus-secreting goblet cells are numerous and cilia are present (1) page 129
- 12. Simple Cuboidal One layer of cuboidal cells resting on a basement membrane (1) page 128 Seen in many types of glands and their ducts (1) page 128 Also found in the kidney (1) page 128
- 13. Stratified Cuboidal Serves a protective function (1) page 130 Can be located in the sweat gland ducts, in the pharynx, and over parts of the epiglottis (1) page 130
- 14. Grandular Specialized for secretory activity (1) page 131 Depends on the complex and highly regulated cellular activities requiring the expenditure of stored energy (1) page 131
- 15. Smooth Muscle Tissue In walls of tubular viscera of digestive, respiratory, and genitourinary tracts.
- 16. Cardiac Muscle Tissue In the Wall of the heart and its function deals with contractions of the heart
- 17. Skeletal Muscle Tissue located in the muscles that attach to bones, extrinsic eyeball muscles, upper third esophagus. The functions include movement of the bones, eye movements, and first part of swallowing.
- 18. Nervous Tissue Located in the brain, spinal cord, nerves. Functions include excitability conduction.
- 19. Elastic Cartilage located in the external part if the ear and the Eustachian tube. Function is to provide structure.
- 20. Blood located in the blood vessels main function is to transport and protect
- 21. Loose ordinary fibrous Stretchable Most widely distributed tissue A lot of space in between the fibers
- 22. Adipose Fat Forms supporting protective pads around the kidneys and other structures. Storage deposit for extra food Acts as an insulating material to conserve body heat
- 23. Reticular Resembles a net or web Forms the framework of the spleen, lymph nodes, and bone marrow Filters injurious substances out of the blood and lymph, and the reticular cells engulf and destroy them.
- 24. Dense Regular connective tissue Consists of fibers packed densely in the matrix Bundles of fibers are arranged in regular, parallel rows Bundles of collagenous fibers and is flexible but possesses great tensile strength
