To throw the weight properly, you will need to buy a good set of throwing shoes. The throwing shoes need to have a rounded bottom and can either be smooth or have a gritty texture.
Best Answer: 1. Dilator pupillae-dilator (radial) muscle-innervated by sympathetic nervous system (Alpha-1 receptors)- increases the size of pupil (mydriasis) 2. Constrictor (circular muscle) pupillae-constricts the pupil (miosis) ex during accommodation reflex. just now. Report Abuse. Radial muscles and circular muscles. When the radial muscles contract the size of the pupil is increased. When the circular muscles contract the size of the pupil is decreased. Changing the size of the pupil controls the amount of light entering the eye.
The ciliary muscles are sphincter muscle that controls the thickness of the lens. Each eye has a ciliary muscle around the lens of the eye.When the muscle contracts the lens gets compressed, and therefore thicker, meaning that it refracts light more (and shortens the focal distance).When it relaxes the reverse is true.ach eye has a ciliary muscle around the lens of the eye.
