phrenic nerve
Transmits electrical impulses to the diaphragm to contract
3 respiratory components of adequate breathing
Respiratory rate, tidal volume, virtually effortless
5 signs of adequate breathing
Good respiratory rate
Equal chest expansion
Regular pattern
Good chest expansion (expands enough)
No head bobbing
Pericardium
Double-walled sac that encloses the heart, gives support, and prevents friction as it
moves
Anterior descending branch
Supplies blood to the left side of the heart
Left coronary artery
one of two arteries from the aorta that nourish the heart; (runs from left side of heart
then divides into the circumflex and left anterior descending branches)
Right coronary artery
, Supplies right atrium and most of right ventricle
Sinoatrial node
pacemaker of the heart
Vessel types
veins, arteries, arterioles, capillaries
Cerebrum
Area of the brain responsible for all voluntary activities of the body
Diencephalon
thalamus and hypothalamus
Thalamus
the brain's sensory switchboard, located on top of the brainstem; it directs messages to
the sensory receiving areas in the cortex and transmits replies to the cerebellum and
medulla
Hypothalamus
A neural structure lying below the thalamus; it directs several maintenance activities
(eating, drinking, body temperature), helps govern the endocrine system via the pituitary
gland, and is linked to emotion and reward.
Brainstem
responsible for automatic survival functions
Spinal cord
Nerves that run up and down the length of the back and transmit most messages
between the body and brain
Cerebellum
