neuro ana (embryology) Flashcards
telencephalon
cerebrum
cerebral cortex, amygdala, basal ganglia, hippocampus, olfactory bulb
telencephalon
mouth-like opening of the archenteron
Blastopore

Endoderm
forms the inner lining of organs
endoderm
Skin cells of epidermis
Neurons
Pigment cells
Ectoderm
neural plate bends up and later fuses to form the hollow tube
neurulation process
serve as the bridge that connects each cerebral hemisphere with the opposite half of the cerebellum.
crus cerebri
traits, shapes, characteristics, and form that can be observed
Phenotype
results of meiosis
haploid cells
(hollow ball) - establish polarity and axes
Blastula
cell differentiation results from mitosis. T/F
F; meiosis (? di ko sure if tama ba toh)
segmentation
Body plan
Cells change their function or phenotype
Cell differentiation
2 sets of chromosomes
diploid cells
Form the anterior end of neural tube
Neural folds
rhombencephalon
metencephalon, myelencephalon
a longitudinal flexible rod of cells that in the lowest chordates
Notochord
stages during development
zygote, blastula, gastrulation, body plan, morphanogenesis
3 primary brain vesicles:
Prosencephalon
Mesencephalon
Rhombencephalon
cells can travel to certain places where they can
still differentiate into their specific forms
cell migration
diencephalon
epithalamus, hypothalamus, thalamus
fluid-filled cavity or the blastula
Blastocoel
Migrate throughout the embryo and give rise to larger range of cells
Neural crest
Results from 2 haploid cells and turns into a diploid once combined
zygote
deliberate termination of a human pregnancy, most often performed during the first 28 weeks of pregnancy
abortion in the ph
cell division producing cells with half of the chromosome strands (23 strands) (1 set)
meiosis
Cardiac and skeletal muscles
Tubules of kidney
Red blood cells
Smooth muscles in the gut
Mesoderm
further develop and differentiate into the brain and the spinal cord of the central nervous system
neurulation process
results of mitosis
diploid cells (4 identical daughter cells)
Medulla
Sensory and motor nuclei and pathways
Cranial nerve nuclei
Caudal end - Spinal cord
Myelencephalon
Formation of specific cells for a specific phenotype
Cell specialization
fertilized egg cell
zygote
Will become the central nervous system
Neural tube
Hollow longitudinal dorsal tube that was formed by the fusion of the neural folds
Neural tube
pregnancy termination prior to 20 weeks’ gestation or a fetus born weighing less than 500 g
abortion according to the National Center for Health Statistics, Centers for Disease Control and Prevention, and World Health Organization
indent of the neural plate in between the neural folds
Neural groove
cell division producing cells with a complete chromosome set (23 pairs)
mitosis
Ponds
Cerebellum
Metencephalon
develops into the organs
mesoderm
consequence of gastrulation
embryonic germ layer
Consequence of morphogenesis
Organogenesis
embryos are what fertilized egg cells called after fertilization. T/F
F; zygote
the irreversible cessation of circulatory and respiratory functions or the irreversible cessation of all functions of the entire brain, including the brain stem
RA 7170
from mono to multiple layer
gastrulation
forebrain
prosencephalon
Unborn offspring, 2-8 weeks after conception
embryo
hypophysis cerebri, thalamus
diencephalon
Study of embryos and their development
Embryology
Movement of cell to produce a certain form or shape based on their programming
Morphogenesis
Collection of multipotent stem cells located at the side of the neural tube
Neural crest
prosencephalon
telencephalon, diencephalon
layers of embryonic germ layer
ecto, meso, endoderm
Lateral longitudinal folds of each side of the neural plate
When fused will give rise to the neural tube
Neural folds
Consequence of cell differentiation
Cell specialization
relays inhibitory signals to the thalamus and basal nuclei to prevent unwanted body movement
tegmentum
forms the exoskeleton
ectoderm
Specific cells combine to take form that would suit its function (combine to form organ)
Organogenesis
stages of baby
zygote, embryo, fetus
fertilization
conception
mesencephalon
midbrain
8 cell stage
morula
1 set of chromosomes
haploid cells
Portion of the ectoderm that will contain the neural folds and crest during neurulation
Neural plate
cavity at gastrula stage
Archenteron
top when referring to brain and head
dorsal
bottom when referring to brain and head
Ventral
Composed of the brain and the spinal
cord
CNS
communicates with sennse organs and voluntary control
somatic ns
Composed of all the nerves outside of
the brain and the spinal cord such as
the somatic nerves and the cranial
nerves i.e. afferent and efferent nerves
PNS
more of
a functional division rather than an
anatomical division
involuntary movement
autonomic ns
communicates with internal organs and glands
autonomic ns
Functions and operations of the different neuroanatomical parts
Functional neuroanatomy
Diseases and other pathological disorders of the different neuroanatomical parts
Clinical neuroanatomy
Macro and microscopic structures of brain
Neuroanatomy
Functions and processes of the brain
Neurophysiology
Drugs and chemicals that alter brain function for treatment purposes
Neuropharmacology
Endogenous chemicals (hormones) produced by the brain or other structures that affects brain functions
Neuroendocrinology
Chemicals that comprises the fluid contents and other parts of the brain
Neurochemistry
Study of diseased or injured brain post death
Neuropathology
Treatment and management of the diseased or injured brain
Neurology
Monitor physiological responses of the body using noninvasive recording and study the resulting psychological consequences
Psychological physiology
Direct manipulation of the brain (invasive) and studying the consequence or effect of manipulation
Physiological psychology
Relationship between anatomy and physiology of the brain
How brain enables the mind
Executive functions
Higher order thinking skills
