It is because of the different neurotransmitters and their receptors.
Sympathetic stimulation of arterioles in skeletal muscle is mediated by epinephrine acting on its β-adrenergic receptors.
Sympathetic stimulation of vasoconstriction occurs as a result of activation of α-1 adrenergic receptors by norepinephrine released by post-ganglionic sympathetic neurons.
Answer:
Vascular Tissues
Explanation:
Angiosperms higher flowering plants it is most diverse group in a plant kingdom nearly 300,000 species of flowering plants are found under this kingdom.The angiosperms have specialised cells and tissues that carry out their metabolic functions and evolved vascular tissues (xylem and phloem) that translocate the water and nutrient to all parts of the plant. They are terrestrial, root system absorbs water and mineral from the soil. the shoot system supports and leaves involved in the process of photosynthesis
