Respiratory System and Anatomy

Respiratory system important for what?

speech and supporting life via breathing

3 of the functional components of speech in Respiratory system

diaphragm, abdominal muscles, ribcage

Phonation

vibration of the vocal folds, source needed to produce speech

Adequate subglottal pressure (Psg ) is needed to?

phonate, produce appropriate loudness, and produce appropriate breath lengths for speaking

Vertebral column

Composed of 34 vertebrae, suspends ribcage and protects the spinal cord

What different types of vertebrae are there and how many?

Cervical (7), Thoracic (12), Lumbar (5), Sacral (5), and Coccygeal (5). 34 total

Lumbar vertebrae are important for what?

bearing weight

Vertebrae 1-7 do what?

protect the spinal cord. If fail to do so, neurological dysfunction can occur. Also connects nerves, arteries, and veins to the brain

Thoracic vertebrae is…

the basis for respiration framework. Attaches to the first rib. the posterior point of contact for the ribs and bony thorax

Pelvic girdle

Point of attachment of the lower extremities to the spinal column and rib cage. Attached to the superior sternum and supports the scapula and shoulder

How many ribs and where do they connect?

12 pairs of ribs. 1-7 connect to the chest bone, 8-10 indirectly connect to the sternum, 11-12 are floating

What’s the pulmonary process?

air travels from nose/mouth → throat → larynx→ trachea → bronchioles → alveoli
