neuro1

4 parts of normal neuromuscular function in breathing

Respond to oxygen and carbon dioxide levels
Signal the respiratory centers in the brain stem

Control the rate and depth of breathing

Conduct impulses from the respiratory centers to the respiratory muscles

chemoreceptors transmit impulses to the

chemoreceptors located in the

central chemoreceptors located in the

impermeable layer of cells that separates the blood from the brain

resp centers located in multiple areas within the

3 types of perpheral nerves

Nerves leave the spinal canal, travel through the neck and into the mediastinum, then over the pericardium, and insert into the diaphragm on either side of the heart

C3 to C5

Arise from the spinal cord at levels T1 to T12
Lie under each rib

Arise from the spinal cord at levels T7 to L1

Diaphragm contracts → pushes down abdominal contents → pressure in the chest drops → causes air to rush in through the trachea → lungs inflate

Largest inspiratory muscle

Used during heavy exercise in healthy persons
Used at rest in those with compromised diaphragmatic function
