6) gait
Imaging used in evaluation of neurological illnesses
CT, MRI, PET
Micro-anatomical organization of the brain
Neurons
Glial cells
Types of glial cells
Macroglia
Microglia
Mental status assessment
Assess mental/emotional status, speech, memory, alertness, reasoning, following command and communication
Cranial nerves assessment
Assess senses (smell, vision, hearing/balance)
Motor function assessment
Assess strength, resistance, coordination, tremors, atrophy
Reflexes assessment
Assess biceps, triceps, tendon reflexes
Sensory functions assessment
Assess reaction to pinprick, vibration, temperature
Gait assessment
Assess walking, balancing
Lobes of the brain
Frontal
Temporal
Parietal
Occipital
Frontal lobe controls
Speech, motor
Separates frontal and parietal lobes
Central sulcus
Gyrus vs sulcus
Gyri: hills
Sulci: valleys
Temporal lobe controls
Hearing
Parietal lobe controls
Sensory
Occipital lobe controls
Vision
Spinal cord function
Control of muscles and reception of sensory information
Brainstem functions
Survival-associated arousal and control of BP/respiration
Cerebellum function
Coordination and balance
Parts of diencephalon

Flow in CSF
2 lateral ventricles –> 3rd ventricle –> 4th ventricle –> SAS –> venous absorption
Where to do spinal tap?
Lumbar SAS below vertebral L1/L2
Separates frontal lobe from temporal lobe
Lateral fissure
Separates the left and right hemispheres
Longitudinal fissure
Planes of section
Coronal
Sagittal
Horizontal
Directional terms
Superior/Inferior
Anterior/Posterior
Dorsal/Ventral
Rostral/Caudal
Types of capillaries
Continuous (nervous system, muscle, fat)
Fenestrated (kidney, endocrine glands, intestinal villi, brain tumors)
Discontinuous (liver, spleen, bone marrow)
Formation of BBB
1) angiogenesis and barrier induction
2) neurovascular unit interactions
3) maturation and maintenance
