Chapter 14 The Brain and Cranial Nerves

A neural cortex is found on the surface of the

Cerebral hemispheres & cerebellum

Superior Sagittal sinus

Cerebrospinal fluid enters the blood circulation at the

Lateral and median apertures

Cerebrospinal fluid enters the subarachnoid space through the

The mamillary bodies of the hypothalamus

Control feeding reflexes

Lobes

Divisions of the cerebral hemispheres that are named after the overlying skull bones are

Telencephalon

During embryonic development which of the following secondary brain vesicles will form the cerebrum

Cerebral peduncles

Nerve fiver bundles on the ventrolateral surface of the mesencephalon

Increased consciousness

Stimulation of the reticular formation results in

Temporal lobe

The auditory cortex is located in the

Inferior colliculi

The medulla oblongata relays auditory information to the

Lateral sulcus

The superior border of the temporal lobe is marked by the

Superior and inferior colliculi

The tectum of the mesencephalon contains the

Septum pellucidum

The thin partition that separates the first and second ventricles is the

Mesencephalic aqueduct

The third and fourth ventricles are linked by a slender canal designated as the

Middle cerebellar peduncle

The tract that links the cerebellum with the pons is the

Pons

The tracts that connect the cerebellum to the brain stem are located in the

Longitudinal fissure

The two cerebral hemispheres are separated by the

Fourth

The ventricle associated with the pons and upper medulla is the

Occipital lobe

The visual cortex is located in the

Arbor vitae

The white matter of the cerebellum forms the

Subarachnoid space

What contains a spider web like network of cells and fibers through which cerebrospinal fluid flows

Diencephalon

What is in between the cerebrum and the brain stem

Pia mater

What structure is covered by many blood vessels and adheres tightly to the surface of the brain

Fornix

A tract of white matter that connects the hippocampus with the hypothalamus is the

Venous circulation

Absorption at the arachnoid granulations returns CSF to the

The anterior nuclei of the thalamus

Are part of the limbic system

Medulla oblongata

Autonomic centres that control blood pressure heart rate and digestion are located in the

Interventricular foramen

Each lateral ventricle communicates with the third ventricle through an

Cerebrospinal fluid

Is secreted by elendymal Cells

Cerebellum

Overseeing the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium are functions of the

12

Pairs of cranial nerves

The basal nuclei

Provide the general pattern and rhythm for movements such as walking

Thalamus

Sensory information is processed and relayed to the cerebrum by the

Pia mater

The layer of the meninges that closely follows every gyrus and sulcus is the

Medulla oblongata

The cardiovascular reflexes are based in the

Astrocytes

The cells that cover the outer surfaces of CNS endothelial cells are the

Vermis

The cerebellar hemispheres are separated by a band of cortex called the

Metencephalon

The cerebellum and pons develop from the

Parietal lobe

The cerebral area posterior to the central sulcus is the

500ml/ day

The choroid plexus produces CSF at a rate of about

Medulla oblongata

The control of heart rate and blood pressure is based in the

Commissural fibers

The corpus callosum is composed of

Falx cerebri

The dural fold that projects into the longitudinal fissure between cerebral hemispheres is called the

Duran folds

The dural sinuses are located in the

Hypothalamus

The floor of the diencephalon is formed by the

Cerebrum

The highest levels of information processing occurs in the

Projection fibers

The internal capsule of the cerebrum is composed of

Olfaction

The only sensation that is received directly by the cerebrum is

Lateral geniculates

The optic tracts carry visual information from the retina to the

Percentral gyrus

The primary motor cortex is the surface of the

Lentiform nucleus

The putamen and globus pallidus are frequently considered to be subdivisions of the

Prefrontal cerebral cortex

The region of the brain responsible for predicting the consequence of events or actions is the

Insula

The region of the cerebral cortex that is medial and deep to the temporal lobe is the

The medulla oblongata

The respiratory rhythmicity centre is located in
