The Speech Process
Nervous System
Respiratory System
Auditory
System
Articulatory
System
Phonatory System
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
The Circle
• Articulatory System (Supralaryngeal)
– Muscles of the vocal tract
– Expends vibratory energy
• Auditory System
– Ear, Muscles, Bones
– Transforms the acoustic waves of speech
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
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
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
Tissue
• Epithelium (cont.)
– Classified by cell layers:
• simple epithelium
• stratified
– Classified by shape:
• squamous
• cubodial
• columnar
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)
A. Loose (3)
A. Collagen Fibers
A. Reticular
Fibers
A. Elastic Fibers
B. Dense Irregular

C. Dense Regular

Tissue
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
Cartilage
Fibrous
Hyaline
Elastic
