neuro ana macro Flashcards
Study of the anatomical structure that is visible (gross) to the naked eye
Gross anatomy
Study of different brain structures that could be seen by the naked eye, include parts that could be observed after a series of cuts (slice) depending on the anatomical plane utilized
Gross neuroanatomy
Curved or rounded projection or division of a bodily organ
Lobes
Deep groove that separates two areas
Fissures
deep groove that separates the left and right cerebral hemispheres (aka cerebral, great longitudinal, median longitudinal, interhemispheric fissure)
Longitudinal fissure
separates parietal and frontal
Central sulcus
separates temporal and frontal
Sylvian fissure/Lateral sulcus
small little space that separates the occipital and temporal
Preoccipital notch
A groove in the cerebral cortex
Superior frontal
Central sulcus of Ronaldo
Lateral sulcus of Sylvius
Superior temporal
Intraparietal sulcus
Sulcus
Sylvius
Lateral sulcus
Ronaldo (Messi fan ako)
Central sulcus
Ridge on the cerebral cortex
Gyrus
Each gyrus is surrounded by sulci. T/F
T
why meron gyrus and sulci?
both increases the surface area of the brain
Primary and secondary areas
Primary motor area
Primary sensory area
Secondary sensory and motor area
Primary and secondary temporal area
Primary and secondary visual area
Primary motor area
Precentral gyrus
Primary sensory area
Post central gyrus
Anterior speech area
Speech production
Broca’s area
Posterior speech area
Language comprehension
Wernicke’s area
disorders of speech with an organic cause
Aphasia
cluster of neurons with the same function in the CNS, located deep within the cerebral hemispheres and brainstem
nucleus (nuclei)
Have robust connections with the cerebral cortex and thalamus
Basal nuclei
Group of subcortical nuclei responsible many for motor control, also motor learning, executive functions and behaviors and emotions
Basal nuclei
Fine-tune the voluntary motor activity and is involved in planning and modulation of movement, memory, eye movements, reward processing, motivation
Basal nuclei
3 parts of Basal nuclei
Caudate nucleus
Putamen
Globus pallidus
part of basal nuclei for cognitive part of emotions
Caudate nucleus
part of basal nuclei for proprioception
Globus pallidus
caudate nucleus + putamen
Caudate striatum
putamen + globus pallidus
Lentiform/Lenticular nuclei
Collection of neuronal bodies found in the voluntary and autonomic branches of the (PNS)
Ganglion
Synaptic relay station between neurons
Ganglion
Responsible for reflexes
Ganglion
For behavioral and emotional responses, especially for emotions needed for survival
Limbic system
located lateral to the thalamus, underneath the cerebral cortex, and above the brainstem
Limbic system
decides the emotion
Hypothalamus
Main 3 structures involved in the limbic system
Amygdala
Hippocampus
Cingulate gyrus
sensory relay center
Thalamus
“Little brain”
Cerebellum
Maintenance of balance and posture, coordination of voluntary movements, motor learning, and cognitive functions
Cerebellum
3 parts of the cerebellum
Cerebrocerebellum
Spinocerebellum
Vestibulocerebellum
part of cerebellum for planning movements and motor learning
Cerebrocerebellum
