Brain Model Flashcards
ID the major part of the brain
Brain stem
ID the major part of the brain being circled & function .
Cerebellum.
Fine tuning of skeletal muscle.
ID the structure
Diencephalon.
ID the structure highlighted
Cerebrum
ID the structure indicated by the bracket & function
Medulla oblongata.
Transmits sensory information to the cerebral cortex.
It regulates autonomic functions : heart rate, respiratory rate, controls vomiting, hiccups, swallowing, coughing, sneezing.
ID the structure indicated by i. Function ?
Pons.
Connects the cerebellum to the brain stem & involved with somatic & visceral motor control. Helps with control breathing movements.
ID the structure indicated by the pointer . Function?
Midbrain.
Processes visual & auditory information & generates involuntary somatic motor responses.
ID the blue hemisphere?
Left hemisphere
ID the pink hemisphere
Right hemisphere
ID the structure indicated by the pointer
Longitudinal fissure
ID the structure highlighted
Lateral sulcus. Separates the temporal lobe from the parietal & frontal lobes
ID the structure indicated by 7
Transverse fissure. Groove separates cerebrum from cerebellum.
Id structure indicated by the pointers
Gyrus:ridges/ projection of brain matter
ID the structure indicated by 3
Sulcus. Depressions or valleys
ID the structure highlighted. Why is it important?
Central sulcus. Separates the frontal & parietal lobes
Distinguish the Anterior & posterior brain
ID the structure highlighted. Why is it important?
Precentral gyrus. Primary motor cortex is found & where skeletal muscle contraction initiates
ID the structure highlighted in pink. Why is it important?
Postcentral gyrus. Primary somatosensory cortex is found.
ID the lobe
Insula lobe.
Function of cerebral cortex ?
Higher order brain:conscious thought
ID the structure highlighted in pink & function ?
Corpus callosum. It’s fiber that connects left & right hemisphere that allows them to communicate in the brain
ID the structure by the pointer
Septum pellucidum. Thin sheath of tissue that separates cerebral spinal fluid & 2 lateral ventricles
ID the structure indicated by pointer
Fornix
ID the structure circled. Function?
Pineal gland. Secretes melatonin
ID the structure indicated by the pointer & function.
Thalamus. Rely sensory input to the cerebral cortex.
ID the structure indicated by 6 & function.
Hypothalamus. Controls body temperature Produces hormones.
ID the structure. Where is it located?
Pituitary gland,sits sella turcica of the sphenoid bone .
ID the structure indicated by black pointer & function.
Infundibulum. Allows hypothalamus to attach to pituitary gland
ID the structure indicated by pointer h.
Mammillary bodies. Gray in the hypothalamus that processes sensations related to smell & controls swallowing.
ID the structure indicated by the pointer.
Midbrain
ID the structure indicated by a.. What is made up of?
Corpora quadrigemmina. Made up of 4 parts : 2 superior colliculi & 2 inferior colliculi.
ID the structure indicated by the white pointer & function ?
Superior colliculi. Mediating visual reflexes
ID the structure indicated by the white pointer & function?
Inferior colliculi. Mediating auditory reflexes
ID the structure indicated by i. Function ?
Pons. Mediates information with cerebellum & the rest of the nervous system. Controls breathing movements : fine tuning of inhalation & exhalation.
What is the pump in front of the medulla oblongata?
Pyramids
ID the structure indicated by A.
Vermis. Band of grey matter.
ID the white structure.Function?
Arbor vitae.white matter
Id the structure inducted by 3 or 2
Lateral ventricles
ID the structure indicated by pointer & function.
Interventricular foramen. Bring cerebral spinal fluid from the lateral ventricle to the third ventricle
ID the structure indicated by 8
Third ventricle
ID the structure indicated by 7 & function?
Cerebral Aqueduct. Carries cerebral spinal fluid from the third to the 4th ventricle
ID the structure indicated by 5
Fourth ventricle
ID the structure indicated by 2
Choroid plexuses. Layer of ependymal cells & capillaries. This where cerebrospinal fluid is made.
