A&P: Speech and Hearing Mechanisms Flashcards
Peripheral
Distal
Medial
Proximal
Prone
On belly
Supine
On the back
Hyper extension
Dorsiflexion
Ipsilateral
Same side
Contralateral
Opposite side
Epithelial tissue
Very little intercellular material
Cells form a tightly packed sheet
Covers surface of human body and lines nearly all body cavities/interconnecting tubes
Connective tissue
Supportive function
Composed primarily of intercellular material = matrix
Stores energy
Areolar
Loose connective tissue, between muscles and organs
Adipose
Between muscles and organs
Lymphoid
Specialized
In tonsils, adenoids, lymph nodes
White fibrous
Dense tissue in ligaments and muscle fascia
Yellow elastic
Within areas requiring recoil
Trachea
Bronchial passageways
Cartilage
Has strength and elasticity
Hyaline
Smooth surface for articulation of bones
Rib cage
Larynx
Provides dense, rigid support
Fibrous
Collagenous fibers between vertebrae; temporomandibular joint surface
Yellow (elastic)
More elasticity
Pinna
Epiglottis
Bone
Hardest CT
Cartilage impregnated with inorganic salts
Blood
Plasma and blood cells
Nervous tissue
Highly specialized communicative tissue
Organs
Aggregates of tissue with functional unity
Muscles
Aggregates of muscular tissue with functional unity
Fascia
Sheet like membranes surrounding organs
Perimysium
Fascia surrounding striated muscle
Ligaments
Binding
Bone to bone
Tendons
Attach muscle to bone or cartilage
Joints
Connect bone to bone or cartilage to cartilage
Joint: synarthrodial
Fibrous
Permit no movement
Joint: Amphiarthrodial
Cartilaginous
Permits limited movement
Diarthrodial
Synovial
Origin
Point of attachment of least mobile element
Insertion
Point of attachment that moves as a result of muscle contraction
Agonist
Muscles that move a structure
Antagonists
Muscles that oppose a given movement
Synergist
Muscles used to stabilize structures
Motor unit
Nerve fiber + muscle fibers to which it attaches
Respiratory
Physical system involved in respiration; provides basic energy of speech production
Phonatory
Utilizes components of the respiratory system to produce voiced sounds
Articulatory
Structures involved in shaping the oral cavity for different speech sound production
Resonatory
Usually oral, pharyngeal, and nasal resonating cavities during vocal fold vibration
