What organ does adrenaline target?

Adrenaline targets various organs,mainly - the Heart, Blood vessels, Smooth muscles(of bronchi, uterus, gastrointestinal tract,bladder etc.), the eye (radial muscles of iris), skeletal muscles (central nervous system also, but weak effect is seen there), metabolic actions (via liver)

It acts via various alpha and beta receptors present at these target organs.

Its main actions can be simplified as below:

Heart-via beta 1 receptors-Adrenaline increases the Heart rate, force of contraction, cardiac output and conduction velocity

Blood vessels-via alpha and beta2 receptors causes constriction mainly in vessels of skin, kidneys and dilatation in vessels of skeletal muscles, liver.

Bronchial smooth muscles - via beta2 receptors- causes broncho dilatation.

Blood pressure- overall rise in blood pressure

Eye- via alpha1 receptors- contraction of radial muscles if iris,therefore increases size of pupil (mydriasis)

CNS- restlessness, apprehension, tremors

Metabolic action- rise in blood glucose levels, lactic acid level, free fatty acid levels.

How adrenaline causes cycloplegia?

Adrenaline, also known as epinephrine, can induce cycloplegia by stimulating the adrenergic receptors in the eye, particularly the alpha-adrenergic receptors. When these receptors are activated, they lead to the relaxation of the ciliary muscle, which is responsible for controlling the shape of the lens for focusing. This relaxation results in the inability to accommodate for near vision, thus causing cycloplegia. Additionally, the overall response of the sympathetic nervous system can inhibit the parasympathetic pathways that facilitate accommodation.
