31

Leg

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)

32

Knee

Medial/ Lateral Collateral Ligament
Anterior/ Posterior Cruciate Ligament
Meniscus: disperses weight and friction

33

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

34

Trauma and Hematoma

Epidural- blow- arterial blood slowly pools between dura and periosteum (skull)

35

Brain

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.
Temporal: hearing
Occipital: vision
Precentral gyrus: motor
Postcentral gyrus: sensory
Ventricles: lateral, 3rd and 4th. Choroid plexus make CSF into subarachnoid space.

36

Inner Layer of Cerebrum

Thalamus: receives, processes, and sends info to cortex.
Hypothalamus: homeostasis
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.

37

Cerebellum

Little brain: balance, coordination, position sense, fine motor, coordination

38

Brainstem

Midbrain: reflex center for visual and auditory stimuli
Pons:bridge between cerebrum and cerebellum
Medulla: respiratory center, heart rate, cough and vomit involuntarily.

39

Spinal Cord

Functions primarily in the transmission of neural signals between the brain and the rest of the body.

40

Skull

Ethmoid bone: olfactory nerve,
Sphenoid- sella turcica, houses pituitary gland "master gland"
Eye Sockets
Foramen Magnum
