The ulnar nerve is formed from the medial cord nerve roots of C7-T1. Originating in the brachial plexus‚ it descends down the arm before passing around the medial epicondyle of the elbow (the so-called funny bone) and then passes between the heads of flexor carpi ulnaris (FCU). It gives some cutaneous branches just before the wrist whilst the motor branches pass around the hook of hamate. Its motor contribution is to all small muscles of the hand except the lateral two lumbricals as well as FCU

Chapter 2 Basis of Derivative Spectrophotometry 2.1 The Main Law of Light Absorption by a Substance Photobiological processes occur under the influence of light of ultraviolet (UV)‚ visible‚ and near infrared spectral regions. Generally‚ values of light flux intensity‚ I‚ and wavelength‚ l are used in optical measurements. The frequency index n is also considered to characterize an absorbed light. Frequency is expressed in reciprocal seconds [cÀ1] and presents itself as the ratio
