3.  Cerebrum  Diencephalon  Brain Stem  Cerebellum

6.  Right & Left hemispheres connected by corpus callosum (bridge of fibers)  Surface = ridges (gyri) & grooves (sulci)  Center for reasoning & memory  Largely determines a person’s intelligence and personality  Composed of 4 lobes: 1. Frontal 2. Parietal 3. Temporal 4. Occipital

7. FRONTAL LOBEConcentration, planning, problem- solving, cognition, frontal eye fields PARIETAL LOBEUnderstanding speech, using grammar and word organization TEMPORAL LOBESensory interpretation. Memory of visual and auditory patterns. OCCIPITAL LOBECombines visual images and visual recognition of objects and shapes.

9. DIENCEPHALON

10.  Thalamus  Integrates sensory impulses (except smell)  Sends motor signals toward spinal cord  Maintains consciousness  Hypothalamus  Produce hormones that control the pituitary  Hunger  Body Temperature  Works with limbic system to control emotions

11. CEREBELLUM

12.  Coordinating Center for motor activity Balance Posture Walking

13. BRAIN STEM

14. Midbrain Controls head and eyes in response to visual stimuli Controls head and trunk in response to auditory stimuli Pons Relay center between cerebrum and medulla Relay center between cerebellum and cerebrum Medulla oblongata Receives info from spinal cord Regulates heart rate, blood pressure, breathing Coughing, sneezing and vomiting

16. There are 4:  2 lateral / right & left (in cerebrum)  Third ventricle (near corpus callosum)  Fourth ventricle (in brain stem) Cavities that fill with cerebrospinal fluid (nutrition & gas exchange for neurons)

19.  Scalp  Skull  Meninges 1. Dura mater = outermost layer 2. Arachnoid mater = middle layer Subarachnoid space = space between arachnoid and pia mater > contains cerebrospinal fluid * Spinal tap 3. Pia mater = thinnest layer

21. Dura mater Contains tough fibrous connective tissue with many blood vessels Arachnoid Thin, netlike layer with blood bessels that reabsorb cerebrospinal fluid Pia Mater Very thin layer with many blood vessels

23. Brain FUNCTION FRONTAL LOBE Concentration, planning, problem-solvimg, cognition, frontal eye fields PARIETAL LOBE Understanding speech, using grammar and word organization TEMPORAL LOBE Sensory interpretation. Memory of visual and auditory patterns. CEREBELLUM Reflex for sensory information. Coordinating Center for motor activity Balance Posture Walking MEDULLA OBLONGATA Receives info from spinal cord Regulates heart rate, blood pressure, breathing Coughing, sneezing and vomiting OCCIPITAL LOBE Combines visual images and visual recognition of objects and shapes. PONS Relay center between cerebrum and medulla Relay center between cerebellum and cerebrum

24. Brain FUNCTION CORPUS CALLOSUM Forms the neural connection between the right and left cerebral hemispheres MAMMILARY BODY Sense of smell (olfaction) OPTIC CHIASMA Where the optic fibers from the medial side of each eye cross PINEAL BODY (gland) Part of the endocrine system. Secretes MELATONIN – the “sleep trigger” hormone; controls sleep-wake cycle and mating behaviors PITUITARY GLAND Regulates hormonal control THALAMUS Integrates sensory impulses (except smell) Sends motor signals toward spinal cord Maintains consciousness HYPOTHALAMUS Produce hormones that control the pituitary Hunger Body Temperature Works with limbic system to control emotions MIDBRAIN Controls head and eyes in response to visual stimuli Controls head and trunk in response to auditory stimuli VENTRICLES Cavities that fill with cerebrospinal fluid (nutrition & gas exchange for neurons)
