5 Matching Questions

  1. Brain Stem
  2. Arachnoid Mater
  3. Post Central Gyrus
  4. PNS
  5. Medulla Oblongata
  1. a *Contains = MEDULLA, PONS & MIDBRAIN
    *Relay station = Sends messages b/w BODY ↔ CEREBRAL CORTEX
    *REGULATES PRIMITIVE FUNCTIONS
    *Contains = Centers that control RESPIRATION, HR, BP
    *RETICULAR ACTIVATING SYSTEM = located in midbrain, pons, medulla, portions of thalamus
    ****Most CRANIAL NERVES ORIGINATE IN BS****
  2. b *Posterior to the CENTRAL SULCUS
    *1⁰ Somatosensory Cortex
    *1⁰ receiving area for SENSORY INFO from the PERIPHERY (trunk and extremities).
  3. c *Delicate middle layer of the meninges; the arachnoid membrane is loosely attached to the pia mater by weblike fibers, which allow for the subarachnoid space
  4. d *SURFACE = WHITE MATTER
    *INTERIOR = GRAY MATTER
    *INFLUENCES AUTONOMIC NERVOUS ACTIVITY (Vasodilation/vasoconstriction)
    *Regulates = RESPIRATION & HR
    *Reflex Center = VOMITING COUGHING, SNEEZING
    *Motor Tracks cross here.
    *Damage = Causes → CONTRALATERAL IMPAIRMENT
  5. e *Cranial Nerves and Ganglia-12 pair-exit skull via foramina
    *Spinal Nerves and Ganglia/Plexus-31 pair
    8 cervical; 12 thoracic; 5 Lumbar; 5 Sacral; 1 coccygeal

5 Multiple Choice Questions

  1. *Shallow grooves on CEREBRAL CORTEX
    *SHALLOW grooves that separate GYRI
  2. Forebrain = divides → Anterior / Posterior portions:
    *Telencephalon (Anterior)
    *Diencephalon (Posterior)
    *Midbrain = Mesencephalon stays the same
    *Hindbrain = partially divides into two parts:
    *metencephalon
    *myelencephalon
  3. *Three membranes that cover the brain and spinal cord,
    *Dura mater=outer most; lines the periosteum of skull; protects the brain
    *Arachnoid mater=Middle menige; impermeabel; loose:
    *Pia mater=inner most meniges; covers contours of brain; forms the chorid plexus in ventricular system
    which provide protection, support & small amounts of nourishment
  4. *Loss of consciousness,
    *Hemiplegia or quadriplegia,
    *Comatose or vegetative state,
    *Inability to speak,
    *Locked-in syndrome,
    *Vertigo,
    *Nystagmus,
    *Dysphagia,
    *Dysarthria,
    *Syncope,
    *Ataxia
  5. Extensive outer layer of GRAY MATTER of the Cerebral hemisphere largely responsible for HIGHER BRAIN FUNCTIONS such as THINKING / PLANNING / JUDGEMENT / PROCESSES SENSORY INFO AND DIRECTS MVMT
    Body's ultimate control and information-processing center

5 True/False Questions

  1. Subthalamus*LOCATION = B/W THALAMUS - HYPOTHALMAS
    *Regulates MVTS produced by the SKELETAL MMS.
    *Assoc. w/ BASAL GANGLIA / SUBSTANTIA NIGRA

          

  2. Occipital Lobe*Function = Control → VOL. MVMT, (Primary motor cortex / Precentral gyrus) INTELLECT, ORIENTATION, SPEECH, BEHAVIOR, PERSONALITY, TEMPER

    *BROCA's area (L SIDE), Speech, concentration,
    *Prefrontal cortex: Controls emotions and judgement

          

  3. Parts of the HindbrainMedulla
    Pons
    Cerebellum

          

  4. Hypothalamus*Receives / integrates info from ANS - REGULATING HORMONES
    *LOCATION = below the THALAMUS
    *MAIN FUNCTION = CONTRL BODY T⁰, APPETITE, SLEEP SEXUAL DESIRE, EMOTIONS (FEAR). REGULATES ADRENAL GLANDS, PITUITARY GLAND
    *Regulates the PARASYM/ SYM NS

          

  5. pineal gland*Produces the hormone MELATONIN = CIRCADIAN RHYTHMS, INTERNAL CLOCK,
