Q

Order of grey and white matter in brain and spinal chord

A

Brain- grey on out, white on in
Spinal chord- grey on in, white on out bc axons should be on out as their sending stuff out

Q

Three layers of the meninges

A

Dura mater - really tough outside
Arachnoid mater - spiderlike and connects dura to pia
Pia mater - tough inside that attaches to brain where blood brain barrier is

25
Types of neurons
Sensory, inter, motor
26
Sensory neurons
Afferent, take info from environment and bring to CNS, bipolar with soma outside of spinal chord for speed
27
Interneurons
Connect sensory to motor, star shaped with tons of dendrites
28
Three types of interneurons and location
Stellate - thalamus Pyramidal - cortex Purkinje - cerebellum
29
Motor neurons
Efferent, from brain stem and spinal chord out to the muscles, some into PNS, unipolar (lots of dendrites, one axon)
30
Glial cell types (glue)
Ependymal, astrocytes, microglial, oligodendroglial, Schwann
31
Ependymal glia
Secretes CSF
32
Astrocytes
Create blood brain barrier
33
Microglial
Forms brains immune system
34
Oligodendroglial cells
Create myelin around axons in CNS
35
Schwann cells
Create myelin in the PNS, can reconnect and repair nerves but only in PNS, not CNS
36
How does nervous system develop
Undifferentiated Neural stem cells turn into progenitors, then blast cells, then specialized cells through differentiation of neurons and glia Stem, progenitor, blast, specialized
37
Development of the CNS
Develops from three enlargements of the embryonic spinal cord (neural tube) Prosencephalon Mesencephalon Rhombencephalon
38
Prosencephalon
Forebrain Telencephalon- forebrain Diencephalon - thalamus, hypothalamus, pineal body
39
Mesencephalon
Midbrain Part of brain stem incl cerebral aqueduct
40
Rhombencephalon
Hindbrain Rest of brain stem Metencephalon - cerebellum, pons Myencephalon - medulla oblongata
41
Ventricles
Four CSF filled cavities in the brain The laterals, third, and fourth
42
Ventricle locations
Laterals - in the tencephalon (forebrain) Third - at midline or brain Fourth - between cerebellum and brainstem
43
Segments of the spinal cord
Cervical - neck Thoracic - midsection Lumbar - mid/lower back Sacral - tailbone
44
12 cranial nerves in order
Olfactory, optic, oculomotor, trochlear, trigemenial, abducens, facial, auditory vestibular, glossopharyngeal, vagus, spinal accessory, hypoglossal
45
Function of cranial nerves in order
Smell, vision, eye movement pupil, eye movement looking up down, face sensation and chewing, eye movement look side, facial expressions, hearing and balance, tongue and pharynx, gut and swallowing, shoulders and neck, tongue
46
Brainstem
Extends from where spinal cord enters skull
47
Hindbrain
Part of brainstem Cerebellum, pons, medulla Motor control and sensory integration, connection to rest of brain, breathing and heart rate regulation
48
Midbrain
Part of brainstem Tectum and tegmentum Superior colliculi relays visual and inferior relays auditory, motor control
49
Dicephalon
Connects brainstem to brain Hypothalamus, thalamus, pineal gland Hormones and all info destined for neocortex
50
Telencephalon
Forebrain Neocortex, basal ganglia and lambic system
51
Basal ganglia
Motor control and learning, Associative learning
52
Order of thalami. Projections
Thalamus starts on top W DM, frontal DM in brain, then counterclockwise thalamus so clockwise brain DM, VA, VL, VLP, LGB, LP, P MGB mid brain and central mid thalamus
53
Lambic system
Amygdala, hippocampus, and cingulate cortex Emotion, personal memories and spatial maps, decision making and executive functions
54
Neocortex
Outer layer of forebrain (lumps and folds) 6 cells thick Two hemispheres divided by the longitudinal fissure
55
Ridges and clefts
Gyri and sulci
56
Locations start at the
Central sulcus Then there is post central, central and precentral as well as superior (top), middle and inferior
57
Primary areas
Receive info directly from senses
58
Secondary areas
Beside primary, take info and do more processing
59
Tertiary areas
Integrate multiple senses to coordinate functions
60
Cellular organization of the cortex
6 layers I on outside, VI on inside Outside 3 receive info from other cortical areas IV is sense, Afferent V and VI send output to motor, efferent
61
How can you tell the function of a part of the cortex by looking at cell layers
If IV is thick, it’s sensory cortex If V and VI are thick it’s motor cortex
