What is Sympathetic nervous system?
The autonomic nervous system is divided into 2 divisions. One is Sympathetic nervous system and the other is parasympathetic nervous system. The SNS (sympathetic nervous system) is responsible for the fight or flight mechanism. It regulates heart rate,blood pressure,pupil dilation,body temperature,sweating and digestion.
How does SNS affect blood pressure ?
The Sympathetic nervous system accelerates the heart and blood pressure during various activities like stress,caffeine,exercise etc. It releases hormones like catecholamines- epinephrine and norepinephrine.. The norepinephrine is released from nuerons ,it reaches the left ventricle where it causes an increase in contractile strength and blood pressure. The epinephrine which is released into circulation by adrenal cortex effects the myocardium and peripheral muscles.
The protein that is expected to be present at varicosity
The catecholamines - epinephrine and norepinephrine. binds to adrenergic receptors. These adrenergic receptors are the protein which are expected to be present at a varicosity.

1. Differentiate between the somatic (motor) nervous system and the sympathetic and parasympathetic branches of the autonomic nervous system in terms of (1) overall anatomic organization (numbers, types of nerves); (2) neurotransmitters made and released by the nerves; and (3) the targets (effectors) of the neurotransmitters’ actions, whether those structures are innervated by one or both branches of the autonomic nervous system, and the effects of activating those structures. 2.Discuss drug absorption as it relates to the route of administration...

there is an experiment. Does diet affect blood pressure? All subjects go through all three treatments. First, they eat a diet with a lot of salt. Their blood pressure is measured. Second, they eat a diet with a lot of sugar. Their blood pressure is measured again. Third, they eat a diet with a lot of protein. Their blood pressure is measured a third time. Describe exactly what an order effect may look like. Why are carry over effects problematic....

When the sympathetic nervous system is activated, you would expect all of the following responses EXCEPT... Select one: O a. contraction of radial ocular muscle. (Contraction of this muscle would dilate the pupil.) b. vasodilation in skeletal muscle. c. insulin secretion. (Insulin is the hormone responsible for reducing blood glucose levels by moving glucose into cells for storage.) d. inhibition of intestinal peristalsis. (Peristalsis is the muscular movements that propel food through the digestive tract.)
