Nervous System Checklist O Levels

Candidates should be able to: (a) state the relationship between receptors, the central nervous system and the effectors (b) describe the structure of the eye as seen in front view and in horizontal section (c) state the principal functions of component parts of the eye in producing a focused image of near and distant objects on the retina (d) describe the pupil reflex in response to bright and dim light (e) state that the nervous system – brain, spinal cord and nerves, serves to co-ordinate and regulate bodily functions (f) outline the functions of sensory neurones, relay neurones and motor neurones (g) discuss the function of the brain and spinal cord in producing a co-ordinated response as a result of a specific stimulus in a reflex action (h) define a hormone as a chemical substance, produced by a gland, carried by the blood, which alters the activity of one or more specific target organs and is then destroyed by the liver (i) explain what is meant by an endocrine gland, with reference to the islets of Langerhans in the pancreas
