New cards

central command

  • voluntary activation (thinking about exercise) of brain parts the control autonomic response to muscle

  • a feedforward signal arising from the CNS involving parallel activation of motor and cardiovascular control centers

  • can occur in anticipation of exercsie

2
New cards

exercise pressor reflex

a feedback mechanism engaged upon stimulation of mechanoreceptors (group 3) and metaboreceptors (group 4)  that trigger activation of cardiovascular control centers 

  • periphreal neural drive 

  • originates in skeletal muscle

3
New cards

mechanoreceptors

  • group 3 receptors that detect stretch/pressure

  • located in tendons of muscle

4
New cards

chemoreceptors

group 4 metaboreflex that detect chemical changes due to metabolites 

  • located in walls of capillaries and venules 

5
New cards

baroreceptors
