Flashcards

Sympathetic vasoconstriction

The sympathetic nervous system generally constricts blood vessels except for those going to the heart and skeletal muscles.

Sympathetic effect: Blood vessels

Sympathetic stimulation causes vasoconstriction in most blood vessels, but not those supplying the heart or skeletal muscles.

Sympathetic effect: Iris

Sympathetic stimulation causes dilation of the pupil (iris).

Sympathetic effect: Bronchi

Sympathetic stimulation causes dilation of the bronchi (airways), allowing increased air flow.

Sympathetic effect: Adipose tissue

Sympathetic stimulation in adipose tissue promotes lipolysis (fat breakdown) and thermogenesis (heat production).
