1. Identify the parts of the neuron on the slide: Cell Body Nucleus Dendrites- Carry impulses TO CELL BODY Axons- Carry impulses AWAY FROM CELL BODY

2. Know this model

3. Know the Meninges

4. Dura Mater- outter most Arachnoid Mater- middle Pia Mater- innermost

5. Parts of the Spinal Chord

6. 3. Know the parts of the Spinal Cord Model Posterior Median Sulcus Anterior Median Fissure Central Canal – filled with CSF Gray Matter- Posterior horn Lateral horn Anterior horn Grey commisure- connects two halves of gray matter White Matter- Poterior funiculus Lateral funiculus Anterior funiculus Spinal Nerve Doral root- carries sensory impulse INTO spinal cord (afferent) Dorsal root ganglion- contains SENSORY NEURON CELL BODIES Ventral root- carries motor impulse AWAY from spinal cord (efferent)

7. 4. Know the Periphereal Nerves Peripheral Nerves ARM: Radial - outside Ulnar - inside Median –middle

8. LEG: Sciatic – can only see on the left foot Obturator- pass through the foramen Femoral- runs down the femur

9. Know the Central Canal and the White and Gray Matter

10. Know the parts of the brain model Cerebrum Cerebral hemispheres seperated by LONGIDUTINAL FISSURE Corpus Callosum- connects the 2 cerebral hemispheres Gyri- Precentral – motor area Postcentral – sensory area Sulci- Central Sulcus Lateral Sulcus Central Lobes- Frontal Parietal Temporal Occipital Broca’s Area- Motor speech area

12. Ventricles Lateral Ventricles 3 rd Ventricle 4 th Ventricle

14. Diencephalon Thalamus – gateway for sensory impulse (except smell) Hypothalamus- PITUITARY GLAND and PITUITARY STALK Pineal Gland – Melatonin Cerebellum Transverse fissure – separate cerebrum from cerebellum Arbor Vitae- pattern of white matter in cerebellum Brain Stem Midbrain Pons Medulla Oblongata

15. Know the Cranial Nerves I.Olfactory- Smell II.Optic – Vision III.Oculomotor- 4 eye muscles IV.Trochlear- 1 eye muscle V.Trigeminal- sensory nerve of face VI.Abducens- 1 eye muscle VII.Facial- muscles for facial expressions VIII.Auditory- equilibrium and hearing IX.Glossopharyngeal- innervates muscle of throat X.Vagus- All major organs XI.Accesory- muscles of neck and shoulder XII.Hypoglossal- muscle of tongue

16. Know the reflex arc 1.Receptor 2.Sensory Neuron 3.Inner Neuron 4.Motor Neuron 5.Effector

17. Experiments Two point discrimination test – determines the density of touch receptors in different areas of the body.

18. Pressure sense acuteness – determine the distribution of touch receptors

19. Adaptation of Touch Receptors – number and strength of sensory impulses changes overt time

20. Referred Pain – where pain is felt in one part of the body when the stimulus is elsewhere

21. Experiments Localization of Taste – mapping of the taste buds Hearing tests Rinne’s – detects conduction deafness Weber’s – detects nerve deafness

22. Visual Acuity- 20/20 1 st number is your eye, 2 nd number is healthy eye

23. What is this chart used for

24. Accommodation- Tests how old your eyes are

25. Blind Spot Determination- The blind spot is created by the area where the optic nerve connects to the retina.

26. Photopupillary Reflex- Whenever the light shines in the eye the iris constricts

27. Negative Color After Image – resynthesize the pigments opposites

28. Know the anatomy of the ear Auricle External Auditory Meatus Tympanic Cavity holds Malleus Incus Stapes Tympanic Membrane Auditory Tube Oval Window Vestibule Semicircular canal Cochlea Round Window Auditory Nerve (Vestibulocochlear)

31. Know the anatomy of the Eye Eyelid Lacrimal Gland Lacrimal Sac MUSCLES OF THE EYE Obicularis Oculi- surrounds eye Superior Rectus – rolls eye up Inferior Rectus- rolls eye down Lateral Rectus- rolls eye outward Medial Rectus- rolls eye inward Superior Oblique- rolls eye down Inferior Oblique- rolls eye up

33. Outer tunic (layer) Sclera- white Cornea- transparent Middle Tunic (layer) Choroid coat- dark Ciliary body with ciliary muscles Suspensory ligaments Lens- transparent Iris- color varies Pupil- hole in iris, allows light waves to reach retina, size of pupil determined by iris Inner Tunic (layer) Retina- contains photoreceptors called RODS and CONES RODS detect light, CONES detect color

39. Anterior cavity- located in front of the lens and contains AQUEOUS HUMOR Anterior chamber- between cornea and iris Posterior chamber- between iris and lens Posterior cavity- located between lens and retina contains VITREOUS HUMOR
