| Question | Answer |
|---|---|
| Define pressure. Equation? | Force exerted on area. p=F/A |
| Boyle's law | Given a gas of constant temperature, it increases the volume of the chamber in which the gas is contained, the pressure will decrease. When volume increases, pressure decreases, and natural law says that air will flow to equalize that pressure. |
| What constitutes the Respiratory system? | 1. oral cavity 2. nasal cavity 3. pharynx 4. trachea 5. lungs |
| This is the term for the body of each vertebra that makes up its anterior portion | corpus |
| this is the lateral protrusion on vertebrae that contains the transverse foramen | transverse process |
| this is the large opening in each vertebra, posterior to the corpus and through which the spinal cord descends. | vertebral canal or foramen |
| these are the openings in the transverse processes of cervical vertebrae through which spinal nerves travel. | transverse foramina |
| this is the flat surface of a vertebra just posterior to the transverse process that enables one vertebra to rest upon another | superior articular facet |
| this is the posterior extension of vertebrae that you can feel when you run your fingers or thumb down the spine | spinous process |
| these are the openings through which spinal nerves enter and exit the spinal cord | intervertebral foramine |
| What are the five divisions of the vertebral column and the number of vertebrae in each division | cervical (7) thoracic (12) lumbar (5) sacral (5-fused) coccygeal (3-4- fused) |
| this is the common name for the inferior-most vertebrae | tailbone (coccyx) |
| these are the common names of C1- and C2, respectively. | atlas (C1) and axis (C2) |
| What bones are included in the pelvic girdle? why are they important in speech? | 1. ilium 2. ischium 3. pubic bone 4. sacrum 5. serve as point of attachment for muscles of forced expiration |
| What bones are included in the pectoral girdle? Why are they important to speech? | 1. clavicle - collarbone 2. scapula- shoulder blade 3. serves as point of attachment for muscles of forced inspiration |
| What are the three general classes of ribs? How many are there of each class? | true ribs (7), false ribs (3), floating ribs (2) |
| What kind of joint is the vertebrocostal attachment? | amphiarthrodial (limited movement, gliding |
| How many pairs of ribs have costal cartilages that attach those ribs to the sternum anteriorly? | 10 |
| Which ribs attach to thoracic vertebrae of the same number and to the rib above? | ribs 2-9 |
| which ribs attach only to the thoracic vertebrae of the same number? | ribs 1, 10, 11, and 12 |
| these are the vertebrae to which the ribs attach posteriorly. | thoracic vertebrae. |
| list the sections of the sternum, from most superior to most inferior. | manubrium sterni, corpus sterni, xiphoid or ensiform process |
| this is the term for the portion of the ribs that attach to the sternum | chondral portion |
| the clavicle and the first rib attach to this portion of the sternum | manubrium sterni |
| this is the name for the connection point between the second rib and the sternum | manubrosternal angle |
| ribs 3 through 7 attach to this portion of the sternum | corpus sterni |
| these are the two tissue types that comprise the bony thorax | bone, cartilage |
| another name for true ribs | vertebrosternal (short cartilage to sternum) |
| another name for false ribs | verebrochondral (long cartilage) |
| another name for floating ribs | vertebral (no connection to sternum) |
| these are two parts of vertebrae to which muscles attach | 1) spinous process 2) transverse process |
| this is another name for the twisting of the ribs during respiration | torque or torquing |
| these are the two directions in which the thoracic cavity enlarges during respiration | 1) vertical (superior to inferior) 2) transverse (anterior to posterior) |
