Flashcards in EMS Anatomy Lab Deck (40)
Quads (quadriceps femoris: rectus femoris, vastus lateralis, medialials, and intermedius)
IT band (iliotibial band) and the TFL
Patella: knee cap (patellar tendon)
Hamstrings (biceps femoris, semimembranosus, semitendinosus)
Medial/ Lateral Collateral Ligament
Anterior/ Posterior Cruciate Ligament
Meniscus: disperses weight and friction
Head and Skull
BBB- so preserve brain separately, Tweeg Hole- preservation fluid.
Meninges: wrapper for important organs. 3: Dura (meningeal arteries- depressions of skull), Arachnoid (spider), Pia (intimate)= soft mother.
Falx cerebri and Tentorum cerebelli
Trauma and Hematoma
Epidural- blow- arterial blood slowly pools between dura and periosteum (skull)
Same pattern in all brains; 3 lbs.
Cell=neurons (100 billion), gaps between neurons- synapse (100 trillion)
Sulci (grooves) Gyri (ridges)
Cerebrum (Frontal higher functions- planning, reasoning, discipline, personality, speech) Phineas Gage (1848- laying down railroad when an explosion happened and an iron flew and pierced him through his left frontal lobe. After he was inappropriate, lost personality, and did cursing.
Parietal: Integration, sensory, and speech.
Precentral gyrus: motor
Postcentral gyrus: sensory
Ventricles: lateral, 3rd and 4th. Choroid plexus make CSF into subarachnoid space.
Inner Layer of Cerebrum
Thalamus: receives, processes, and sends info to cortex.
Hippcampus: learning, short term memory converted to long term memory.
Limbic system: smell, emotions, instinct.
Stroke: Inadequate supply, no oxygen, cells die. (Contralateral weakness to stroke) STR (SMILE, TALK, RAISE arms).
Alzheimer's: Proteins cleaved wrong way, clump together and form plaques that deposits around the nerves. Block cell to cell signaling.
Little brain: balance, coordination, position sense, fine motor, coordination
Midbrain: reflex center for visual and auditory stimuli
Pons:bridge between cerebrum and cerebellum
Medulla: respiratory center, heart rate, cough and vomit involuntarily.
Functions primarily in the transmission of neural signals between the brain and the rest of the body.
