Term
Boyle's Law
Definition
P*V=K
Term
In Boyle's Law, P is _______(1). V is __________(2). And K means that these two things multiplied together produce a _______(3) product. Because of this, if P goes down, what must happen to V? _________(4)
Definition
(1) pressure
(2) volume
(3) constant
(4) increase
Term
With respect to respiration, Boyle's Law requires that air must flow out of the lungs during expiration because thoracic _____(1) decreases, so ______(2) within the lungs increases, and air moves from an area of _______(3) to an area of _________(4).
Definition
(1) volume
(2) pressure
(3) high pressure
(4) low pressure
Term
The lungs are protected by an elaborate bony structure that includes the ribs and bones with which they articulate dorsally and ventrally. One dorsal boney structure with which ALL ribs articulate directly is the _____(1), while, on the other side of the body, only SOME ribs articulate directly with the ___________(2).
Definition
(1) spine
(2) sternum
Term
Name the three types of ribs, the number of each type, and the feature that distinguishes each type from the other two:
1._______(name) _____(#) ____(feature)
2._______(name) _____(#) ____(feature)
3._______(name) _____(#) ____(feature)
Definition
1. true ribs; 1-7; articulate ventrally with the sternum

2. false ribs; 8-10; connect to costal cartilage that connects to sternum

3. floating ribs; 11-12; articulate only with the spine and do not attach to any structure on ventral side.
Term
There are five classes of vertebrae. Name the classes with the number of segments in each class, from rostral-most to caudal-most:
1.______
2.______
3.______
4.______
5.______
Definition
1. Cervical, 7
2. Thoracic, 12
3. Lumbar, 5
4. Sacral, 5
5. Coccygeal, 2-4
Term
The sternocleidomastoid receives its motor supply from cervical nerves, and possibly from CN _______ (name and number).
Definition
XI, spinal accessory.
Term
The lungs and chest wall aren't connected by mechanical means (like a tendon or ligament). Instead the lungs are surrounded by a membrane called the ________(1), and the inner chest wall is covered by a membrane called the ______(2). The two membranes adhere to each other through a mechanism called _________(3).
Definition
(1) visceral pluera
(2) parietal pluera
(3) plueral linkage
Term
There are two sets of intercostal muscles. One set raises the ribs, thus aiding inspiration. These are the ___________(1). Another set lowers the ribs, thus aiding expiration. These are the ______(2). These are innervated by _____(3).
Definition
(1) external intercostals
(2) internal intercostals
(3) T2-T12
Term
The segmented, ventral-medial abdominal muscle which compresses abdominal contents for expiration
Definition
rectus abdominis
Term
The upper dorsal inspiratory muscle which originates on the spinous processes of vertebrae C7-T3 and fans caudo-laterally to insert on ribs 2-5, innervated by T1-T4.
Definition
serratus posterior superior
Term
Inspiratory muscles on the sides of the neck which run from transverse processes of vertebrae C3-C7 down to the first two ribs, and receive their motor supply from C2-C3
Definition
scalenes
Term
There are three layered abdominal muscles lateral to the ventral-medial segemented muscle that's always so prominent on the cover of men's fitness magazines. In order, from superficial to deep, these three layered muscles are _______(1), _______(2), and ________(3).
Definition
(1) external obliques
(2) internal obliques
(3) transverse abdominis
Term
An expiratory muscle of the back which originates on lower thoracic and upper lumbar vertebrae, and extends upward and to the side to grab onto the lower ribs, innervated by T9-T12, is _________.
Definition
serratus posterior inferior
Term
The deep chest muscle which is potentially well positioned through its vertical orientation to help with inspiration, attaches rostrally to the corocoid process of the scapula and caudo-medially to ribs 2-5, innervated by C5-6, is ______
Definition
pectoralis minor
Term
The long line of dorsal inspiratory muscles that run down the spine from C7-T11, and are positioned to pull up on the ribs are:
Definition
costal elevators
Term
The potentially inspiratory (and rather pretty) muscle with jagged knife-like insertions on the ribs which originates on the scapula and courses forward under the arm, and innervated by C5-C7 (and maybe T1-T2), is
Definition
serratus anterior
Term
The innervation of the diaphragm is the phrenic nerve, which is comprised of fibers from what spinal nerves?
Definition
C3-C5
Term
The innervation for all the ventral abdominal muscles comes from what nerves? ______(1) All these muscles participate in which phase of respiration? ____(2)
Definition
(1) T6-T12
(2) expiration
Term
If the volume of a syringe (or the thorax) increases, then pressure in the syringe/thorax must _____.
Definition
decrease
Term
To blow out birthday candles, muscles you're likely to use in your expiratory effort are:_______
Definition
external oblique and serratus posterior inferior
Term
If your phrenic nerve (alone) is severed, then you will use accessory muscles of _______ to breathe.
Definition
inspiration
Term
The central tendon is the point of insertion for fibers from what muscle?
Definition
diaphgram
