Chapter 13 Flashcards
What is the innervation for the diaphragm?
phrenic nerve
What plexus does the phrenic nerve rise from? and what spinal nerves form this?
phrenic plexus
Cervical spinal nerves 3-5 (“three four and five keep us alive”)
What innervates the neck muscles (ie scalenes)?
cervical spinal nerves
What innervates the thoracic muscles and levator costarum?
thoracic spinal nerves
What innervates muscles of the arm and shoulder:
pectoralis major
pectoralis minor
serratus anterior
What nerves form this?
Nerves from the brachial plexus
Formed by spinal nerves C4-C7 and Throacic Nerve T1
What innervates teh Sternocleidomastoid?
Crainial Nerve XI
What innervates the thoracic expiratory muscles?
thoracic spinal nerves
what innervades the abdominal expiratory muscles?
thoracic and lumbar spinal nerves
What are volumes?
discrete units that refer to the amount of air in a given space
partioning off the respiratoy system so that we may get an accurate estimate of the amount of air each compartment can hold
What are capacities?
functional units that refer to a combination of volumes that express physiological limits
functional units that refer to combinations of voluemes that express physiological limits
measurment = mililiters or cubic centimeters 1 ml = 1cc
What is normal resting respiration per minute for an adult?
12-18 cycles per minute
How can you measure volume?
wet spirometer
How can you measure pressure?
U-tube monometer
pressue measured in cm/H2O
How would you measure airflow during speech?
hot-wire anemometer
How would you measure large volumes like vital capactiy?
pneumotachometer witha large flow screen
