12. The Speech Process Nervous System Respiratory System Phonatory System Articulatory System Auditory System

13. The Circle Nervous System –Encodes ideas –Control of speech muscles Respiratory System –Generation of air pressure –Drives the sound generator Phonatory System (Laryngeal) –Muscles of the larynx –Vibratory energy

14. The Circle Articulatory System (Supralaryngeal) –Muscles of the vocal tract –Expends vibratory energy Auditory System –Ear, Muscles, Bones –Transforms the acoustic waves of speech

15. General Terms Anatomy: The study of the structure of an organism Physiology: The study of the function of the living organism and its parts as well as the chemical processes involved Related fields: Cytology, Histology, Osteology, Myology, arthrology, neurology

16. Building Blocks of Anatomy: Tissue Cells & Tissues: –100 trillion cells 1) Function: –ingestion of nutrients –breakdown & utilization of nutrients; metabolic, discharge of wastes –Four Basic Types of Tissue: epithelium connective tissue nerve muscle

17. Tissue Epithelium –Sheets of cells covering external surfaces of the body & line cavities –Cells; little intracellular substance, adhere, avascular –Function: Protection & Absorption –Glandular, myepithelium, neuroepithelium

18. Tissue Epithelium (cont.) –Classified by cell layers: simple epithelium stratified –Classified by shape: squamous cubodial columnar

19. Tissue Connective –Types: Connective tissue proper, cartilage & bone 1) Connective tissue proper: few living cells nonliving intracellular material 3 types of tissue: collagen, elastic, reticular Loose Dense (irregular, regular: tendons, ligaments)

20. A. Collagen Fibers A. Reticular Fibers A. Elastic Fibers B. Dense Irregular Connective Tissue C. Dense Regular Connective Tissue A. Loose (3) Connective Tissue

21. Tissue Connective Tissue Proper (cont.) –Tendon: regular connective tissue; attach muscle to bone –Ligaments: regular connective tissue; connects bones and cartilage's 2) Cartilage: –rigid consistency, flexibility, slight elasticity –form resistant to pressure (unlike CTP) –composed of matrix (cytoplasm) –3 types: Hyaline, Elastic, Fibrous

22. Cartilage Hyaline Elastic Fibrous

23. 3 Types of Cartilage Hyaline: –fine network of collagen fibers –most common type –most rigid form –found in nose, larynx, rib cage (between bony ribs & sternum) Elastic: –dense network of elastic & some collagen fibers –less rigid –form to external ear Fibrous: –cells occur in rows & collagen fibers in bundles –Found in the disks between the vertebrae
