Temporal Lobe Responsible for: Speech Memory Hearing Vision
Occipital Lobe Responsible for: Controling vision Color recognition
Parietal Lobe Responsible for: Integrating sensory information from various parts of the body Knowledge of numbers and their relations The manipulation of objects
Somatosensory Cortex
Frontal Lobe Responsible for: Motor function Problem solving Spontaneity Memory Language Initiation Judgement Impulse control Social/Sexual behavior
Cerebellum Responsible for: The integration of sensory perception Regulation and coordination of voluntary motor movement. The maintenance of posture and balance.
Medulla Oblongata Responsible for: Controlling heart rate Constriction and dilation of blood vessels Respiration Digestion Reflex center for vomiting, coughing, sneezing, swallowing, and hiccupping
Function of a Neuron in Impulse Transmission Transmits information within the nervous system
Head Injury and Treatment Head Injury- any trauma that leads to injury of the scalp, skull, or brain Penetrating trauma- when objects such as screwdrivers, knives, or any sharp objects, penetrate the skull. Blunt head trauma-the result from direct blow, or from a rapid deceleration force, such as a fall or a car accident. -Serious head injuries may cause : Changes in personality, emotions, or mental abilities Concussions Speech and language problems Loss of sensation, hearing, vision, taste, or smell Seizures Paralysis Coma
External Head Injuries: External head injury- most commonly, trauma to the scalp
Head and neck pain Minor head injuries may result to headache or dizziness. Sensation of spinning or light- headedness. Some people also may have mild confusion, Nausea Become more irritable. Swelling Symptoms
Treatments Ice should be applied Bed rest Fluids A mild pain reliever such as aspirin or acetaminophen (Tylenol), if necessary If there is a cut, an immunization would be given if needed to prevent tetanus
Internal Head Injuries: Internal head injury- may involve the skull, the blood vessels within the skull, or the brain.
Symptoms unconsciousness abnormal breathing obvious serious wound or fracture bleeding or clear fluid from the nose, ear, or mouth disturbance of speech or vision pupils of unequal size weakness or paralysis dizziness neck pain or stiffness seizures vomiting more than two timesvomiting loss of bladder control
Treatments if necessary to relieve pressure, surgery must be done to decompress the braindecompress If there's swelling, apply an ice pack or cold pack If there's bleeding, apply a sterile bandage Call for help if person lost consciousness, or vomits more than once If there is a spinal injury, do not move the body
Etiologies, Symptoms, Treatment of Brain Abscesses Brain abscess is a focal infection, which begins when organisms are inoculated into the brain parenchyma, usually from a site distant from the central nervous system (CNS). The 3 mechanisms of entry: Direct Extension Hematogenous Following penetrating head injury or neurosurgery The mortality rate from brain abscess is currently approximately 10%.
Treatment The increased intracranial pressure and starting intravenous antibiotics antibiotics Surgical drainage of the abscess
