Overview of the Brain Meninges, Ventricles, Cerebrospinal Fluid, and Blood Supply The Hindbrain and Midbrain Forebrain Cerebrum
100
What is the cerebrum
This is about 83% of the brain’s volume and consists of a pair of half globes called the cerebral hemispheres
100
What is the transverse sinus
This sinus runs horizontally from the rear of the head toward each ear
100
What is the medulla oblongata
The myelencephalon becomes the adult structure of this
100
What is the diencephalon
The three structures that arise from this are the thalamus, hypothalamus, and epithalamus
100
What is the frontal lobe
This lobe Lies immediately behind the frontal bone, superior to the eyes. It is chiefly concerned with voluntary motor functions, motivation, foresight, planning, memory, mood, emotion, social judgment, and aggression.
200
What is rostral
One of the two directional terms used in the description of CNS anatomy, this means "toward the nose"
200
What is the superior sagittal sinus
This sinus is found just under the cranium along the median line
200
What are cerebellar peduncles
Posteriorly, the pons consists mainly of two pairs of thick stalks called this
200
What is the thalamus
This is an ovoid mass perched at the superior end of the brainstem beneath the cerebral hemisphere and is the gateway to the cerebral cortex
200
What is the occipital lobe
This lobe Is at the rear of the head, caudal to the parieto–occipital sulcus and underlying the occipital bone. It is the principal visual center of the brain
300
What is the corpus callosum
At the bottom of the longitudinal fissure, the hemispheres are connected by a thick bundle of nerve fibers called this
300
What are ventricles
The brain has 4 internal chambers called this
300
What is the midbrain
This is a short segment of brainstem that connects the hindbrain and forebrain and is a result of the maturing of the mesencephalon
300
What is the hypothalamus
This is the major control center of the endocrine and autonomic nervous systems
300
What is the limbic system
This system is an important center of emotion and learning. It is a ring of structures on the medial side of the cerebral hemisphere, encircling the corpus callosum and thalamus.
400
What is gray matter
This type of matter forms a surface layer called the cortex over the cerebrum and cerebellum
400
What is an interventricular foramen
Through a tiny pore called this, each lateral ventricle is connected to the third ventricle, a narrow median space inferior to the corpus callosum.
400
What is reticular formation
This is loose web of gray matter that runs vertically through all levels of the brainstem
400
What is the epithalamus
This is a very small mass of tissue composed mainly of the pineal gland, the habenula, and a thin roof over the third ventricle
400
What are stellate cells
These specific types of cells have spheroidal somas with dendrites projecting for short distances in all directions.
500
What is the fifth week
By this week, the forebrain divides into the telencephalon and diencephalon
500
What is the blood barrier system
This system strictly regulates what can get from the bloodstream into the tissue fluid of the brain.
500
What is habituation
This is a process in which the brain learns to ignore repetitive, inconsequential stimuli while remaining sensitive to others.
500
What are granule cells
These type of cells are the most abundant type of neuron in the entire brain
500
What is insula
This is a small mass of cortex deep to the lateral sulcus, made visible only by retracting or cutting away some of the overlying cerebrum. Plays roles in understanding spoken language, in taste, and in integrating information from visceral receptors.
