It also innervates the ciliary muscles. These muscles connect the iris to the choroid. Contraction of the muscle alters the curvature of the lens which allows individuals to focus the lens on near objects (Figure 1).Smooth Muscle. Smooth muscle is made up of cells that contain a single central nucleus. The cells stick together and are connected by specialised cell junctions, called gap junctions. The cells are spindle shaped, and the nucleus is central. This diagram shows a few of the cells that can be seen in the stained section below.Neurons, or nerve cell, are the main structural and functional units of the nervous system.Every neuron consists of a body (soma) and a number of processes (neurites).
