Ventricle Structures
These are the interconnected brain cavities that produce, store, and circulate the cerebrospinal fluid.
What are ventricles?
(Page 560)
This circulates the CSF and is secreted by the choroid plexus.
What are ventricular cavities?
(Page 69)
The definition of meninges.
What are three protective membranes (dura, arachnoid, and pia) that cover the central nervous system?
(Page 549)
The definition of falx cerebri.
What is the large, sickle-shaped extension of dura between the cerebellar hemispheres?
(Page 543)
The definition of diencephalon.
What is the inner part of the brain that is located beneath the cerebral hemispheres and includes the thalamus and hypothalamus?
(Page 541)
The names of the four ventricles.
What are the 2 lateral ventricles, the third ventricle, and the fourth ventricle?
(Week 1, Slide 74)
This is the clear fluid that is produced in the ventricular cavity that protects the CNS by forming a cushion in the subarachnoid space around the brain and spinal cord - also known as CSF.
What is cerebrospinal fluid?
(Page 538)
The definition of dura mater.
What is the gray outermost membrane, that consists of dense, fibrous connective tissue and provides the maximum meningeal protection to the CNS?
(Page 79)
This is the largest dural reflection.
What is the falx cerebri?
(Page 80)
This is the name of the masses that form the central core of the brain.
What are the subcortical nuclear masses that form the central core of the brain?
(Page 54)
These ventricles are C-shaped structures that form an arch that also consist of a central part, with 3 extensions: anterior, posterior, and inferior.
What are the lateral ventricles?
(Page 69)
This protects and supports healthy cell function in the brain and in the spinal cord.
What are the ventricles?
(PPT 1, Slide 75)
The attachment of the dura mater.
What is attached to the inner surface of the skull and overlies the underlying arachnoid?
(Page 79)
The shape of the falx cerebelli vertical extension.
What is the triangular-shaped vertical extension?
(Page 80)
The two major substructures of the diencephalon.
What are the thalamus and hypothalamus?
(Page 54)
This ventricle is a narrow vertical space between the two thalami and is rostrally connected to the lateral ventricles through the interventricular foreamen of Monro.
What is the third ventricle?
(Page 72)
These cells are in the inner wall of the interconnected ventricular cavities and prevent diffusions of substances from the CSF into the brain.
What are the ependymal cells?
(Page 69)
The definition of pia mater.
What is the innermost layer of the meninges and is also a thin, transparent, collagenous (connective tissue) membrane that is closely attached the the surface of the brain.
(Page 83 and 553)
The definition of tentorium cerebelli.
What is the dural extension that covers the cerebellum and the floor of the cranium?
(Page 559)
The thalamus functions as this.
What functions as a information relay center?
(Week 1, Slide 62)
This ventricle has the tegmentum of the pons and medulla that constitute the triangular floor while the cerebellum forms its roof.
What is the fourth ventricle?
(Page 72)
This is a common pathological condition associated with the accumulation of the cerebrospinal fluid in the brain ventricles secondary to its impaired absorption.
What is hydrocephalus?
(Page 546 and 69)
The definition of the arachnoid membrane
What is a thin, nonvascular membrane between the internal pia mater and the external dura mater?
(Page 80)
This arises from the petrous portion of the temporal bone.
What is the tentorium cerebelli?
(Page 80)
The special circuitry in the hypothalamus regulates for these things.
What are the regulations of body temperature, water and food intake, sugar metabolism, sexual behavior, and emotional state?
