QuestionAnswer
SKELETAL MUSCLE VOLUNTARY - SUBJECT TO CONSCIOUS CONTROL, ALTERNATING DARK AND LIGHT BANDS, Z LINES AND M LINES, LONG MUSCLE FIBERS
CARDIAC MUSCLE HEART MUSCLE - PUMPS BLOOD. INVOLUNTARY - AUTORYTHMIC. MADE OF CARDIOMYOCYTES LINKED BY INTERCALATED DISKS WITH ELECTRICAL GAP JUNCTIONS. RECTANGLE SHAPED WITH FORKED ENDS
SMOOTH MUSCLE MADE OF MYOCYTES. IN WALLS OF BLOOD VESSELS AND MAY BODY CAVITIES AND VISERA (ORGANS), MAINTAINS MUSCLE TONE TO KEEP FROM COLLAPSING IN. NO SARCOLEMAS OR ZLINES. OVAL SHAPE...FAT IN THE MIDDLE AND TAPERED AT THE ENDS
A BANDS THE OVERLAP OF ACTIN AND MYOSIN FIBERS
I BANDS LIGHT ACTIN FILAMENTS
Z LINE PLAQUE PROTEINS THAT ANCHOR THE ACTIN FILAMENTS
M LINE CONNECTS THE MYOSIN FILAMENTS
TREPPE A MODERATE FREQUENCY OF REPETITIVE STIMULATION. THE MUSCLE RELAXES FULLY IN BETWEEN CONTRACTIONS AND SUCCESSIVE TWITCHES ARE STRONGER
INCOMPLETE TETANY A HIGHER FREQUENCY OF STIMULATION. THE MUSCLE DOES NOT FULLY RELAX BETWEEN CONTRACTIONS. FORCE OF EACH CONTRACTION BUILDS ON THE PREVIOUS CONTRACTION.
COMPLETE TETANY FREQUENCY OF STIMULATION DOES NOT ALLOW FOR RELAXATION BETWEEN CONTRACTIONS.
RECRUITMENT MOTOR UNIT RECRUITEMENT. RESPONSIBLE FOR SMOOTH MOVEMENT. SMALLER MOTOR UNITS ARE ACTIVATED FIRST AND LARGER MOTOR UNITS ARE ACTIVATED AS MORE STRENGTH IS NEEDED. ALLOWS FOR LESS MUSCLE FATIGUE AS MUSCLES TAKE TURNS ACTIVATING.
ISOMETRIC MUSCLE TENSION WITH NO CHANGE IN LENGTH
ISOTONIC (CONCENTRIC) TENSION RISES TO MEET RESISTANCE AND THEN SHORTENS
ISOTONIC (ECCENTRIC) MUSCLE LENGTHENS TO MEET RESISTANCE
STRUCTURAL TYPES OF NEURONS MULTIPOLAR, BIPOLAR AND UNIPOLAR.
MULTIPOLAR NEURON MANY EXTENSIONS FROM THE CELL BODY. MOST COMMON. ALL MOTOR NEURONS AND INTERNEURONS ARE MULTIPOLAR
BIPOLAR NEURON ONE AXON AND ONE DENDRITE EXTEND FROM THE CELL BODY. NOT COMMON IN ADULTS. IN SPECIAL SENSE (EYES, NOSE)
UNIPOLAR NEURON CELL BODY HAS A SHORT PROCESS LEADING TO ONE LONG AXON WITH DENDRITES ON ONE END. THESE ARE IN SENSORY NEURONS AND PNS GANGLIA
CNS GLIAL CELLS (NEUROGLIA) OLIGODENDRICYTES, EPENDYMAL, MICROGLIA, ASTROCYTES
OLIGODENDRICYTES OCTOPUS SHAPED. MYELINATED. WRAPS AROUND NERVE FIBERS
EPENDYMAL LINES THE BRAIN AND SPINAL CORD. CILIATED - ASSISTS WITH MOVEMENT OF CSF
MICROGLIA SPIDER LIKE PHAGOCYTES
ASTROCYTES MOST ABUNDENT. PROVIDE A BARRIER BETWEEN CAPPILARIES AND NERUONS. HELPS FORM THE BLOOD BRAIN BARRIER. CONTROLS THE CHEMICAL ENVIRONMENT
PNS GLIAL CELLS SCHWANN CELLS AND SATELLITE CELLS
SCHWANN CELLS MYELINATED - CELLS WRAP AROUND THE AXONS. MYELIN IS NECESSARY FOR REGENERATION OF NERVE FIBERS (NOT POSSIBLE IN THE CNS). HELPS SIGNAL CONDUCTION OF NERVE FIBER.
SATELLITE CELLS WRAP AROUND CELL BODIES. ELECTRICALLY INSULATES THEM AND REGULATES THE CHEMICAL ENVIRONMENT
NEUROTRANSMITTER TOXINS ACH INHIBITORS, ACHE INHIBITORS AND ACHR INHIBITORS
CNS GREY MATTER CELL BODIES NUCLEI
CNS WHITE MATTER - BUNDLES OF NERVE FIBERS TRACTS
PNS GREY MATTER CELL BODIES GANGLIA
PNS WHITE MATTER - BUNDLES OF NERVE FIBERS NERVES
T-TUBLE CARRIES ELECTRICAL CURRENTS FROM THE CELL SURFACE TO THE INTERIOR WHEN THE CELL IS STIMULATED
SARCOPLASMIC RETICULUM FORMS A WEBLIKE STRUCTURE AROUND EACH MYOFIBRIL AND IS A RESERVOIR OF CA2+. WHEN STIMULATED IT RELEASES CA2+ INTO THE CYTOSOL TO ACTIVATE CONTRACTION
MOTOR NEURONS NERVE CELLS THAT STIMULATE SKELETAL MUSCLES
MOTOR NERVE FIBERS MOTOR NEURON AXONS THAT LEAD TO THE MUSCLES
SLOW TWITCH FIBERS RED MUSCLES. LONG/SLOW TWITCHES. DO NOT FATIGUE EASILY (E.G SOLEUS)
FAST TWITCH FIBERS WHITE MUSCLES. QUICK RESPONSES. FATIGUE EASILY
REFRACTORY PERIOD A PERIOD WHERE THE MEMBRANE OF A NEURON CANNOT BE STIMULATED
GYRUS THE BUMPS ON THE SURFACE OF THE CEREBRAL CORTEX (BRAIN)
SULCUS THE GROOVES IN THE SURFACE OF THE CEREBRAL CORTEX (BRAIN)
FISSURES DEEP GROOVES DIVIDING THE CEREBRUM INTO LOBES
POST CENTRAL GYRUS BEHIND THE CENTRAL GYRUS. PRIMARY SOMATOSENSORY CORTEX
PRE CENTRAL GYRUS IN FRONT OF THE CENTRAL GYRUS. PRIMARY MOTOR CORTEX
SPECIAL SENSES TASTE, VISION, AUDITORY, OLFACTORY
BROCAS AREA INVOLVED IN OUR ABILITY TO SPEAK. PRODUCTION OF SPEECH
WERNIKE'S AREA IMPORTANT FOR LANGUAGE DEVELOPMENT. COMPREHENSION OF SPEECH. LOCATED IN THE LEFT TEMPORAL LOBE.
BASAL NUCLEI AKA BASAL GANGLIA. GREY MATTER OF THE CNS THAT CONTROLS MOVEMENT.
OCCIPITAL LOBE VISION
PARIETAL LOBE SENSORY, TOUCH, PAIN, SPACE
FRONTAL MOTOR AND IMPULSE CONTROL
TEMPORAL HEARING (AND SMELL), LONG TERM LEARNING VIA HIPPOCAMPUS
PROJECTION FIBERS CONSIST OF EFFERENT AND AFFERENT FIBERS UNITING THE CORTEX WITH LOWER PARTS OF THE BRAIN AND SPINAL CORD.
COMMISURAL FIBERS TRANSVERSE FIBERS IN THE WHITE MATTER THAT CONNECT THE TWO HEMISPHERES
ASSOCIATION FIBERS AXONS THAT CROSS OVER ONE ANOTHER WITHIN THE SAME HEMISPHERE
MENINGES DURA MATTER, ARACHNOID, PIA MATTER
CSF FLOW 1. LATERAL VENTRICAL 2. INTRAVENTRICULAR FORAMEN 3. THIRD VENTRICAL 4. CEREBRAL AQUEDUCT 5. 4TH VENTRICLE 5. SUBARACHNOID SPACE 7. SUBARCHNOID GRANULES
