Chapter 17 Gross Anatomy Of The Brain And Cranial Nerves

The central nervous system/peripheral nervous system consists of the brain and spinal cord

the most superior portion of the brain includes the cerebral hemispheres/brain stem

True or False. Deep grooves within the cerebral hemispheres are known as gyri

On the ventral surface of the brain, you can observe the optic nerves and chiasma, the pituitary gland, and the mammillary bodies. These externally visible structures form the floor of the...

the inferior region of the brain stem the medulla oblongata/cerebellum houses many vital autonomic enters involved in the control of heart rate, respiratory rhythm, and blood pressure.

directly under the occipital lobe of the cerebrum is a large cauliflower like structure known as the...

the outer cortex of the brain contains the cell bodies of cerebral neurons and is knowns as white matter/gray matter

the brain and spinal cord are covered and protected by three connective tissue layers called...

where is the primary auditory cortex found?

where is the primary motor cortex found?

where is the primary somatosensory cortex found?

where is the olfactory cortex found?

where is the primary visual cortex found?

where is the broca's area found?

which of the following structures is part of the brain stem?

review the human brain page 297

review the states on page 297

review the structures of the human brain stem and diencephalon on page 298

site of regulation of body temperature and water balance; most important autonomic center

site where medial fibers of the optic nerves cross

located in the midbrain; contains reflex centers for vision and audition

responsible for regulation of posture and coordination of complex muscular movements

important synapse site for afferent fibers traveling to the sensory cortex

contains autonomic centers regulating blood pressure, heart rate, and respiratory rhythm, as well as coughing, sneezing, and swallowing centers

large commissure connecting the cerebral hemispheres

fiber tract involved with olfaction

connects the third and fourth ventricles

encloses the third ventricle

embryologically, the brain arise from the rostral end of a tubelike structure that quickly becomes divided into three major regions. groups of structures that develop from the embryonic brain are listed below. designate the embryonic origin of each group as the hindbrain, midbrain, or forebrain.

1.) the diencephalon, thalamus, optic chiasma, and hypothalamus

2.) the medulla oblongata, pons, cerebellum

3.) the cerebral hemispheres

what is the function of the basal nuclei

what is the striatum and how is it related to the fibers of the internal capsule?

a brain hemorrhage within the region of the right internal capsule results in paralysis of the left side of the body. explain why the left side rather than the right side is affected.

explain why trauma to the brain stem is often much more dangerous than trauma to the frontal lobes.

explain how patients in a vegetative state can have no damage to their cerebral cortex and yet lack awareness of their environment.

patients in a vegetative stated will often reflexively respond to visual and auditory stimuli. where in the brain are the centers for these reflexes located?

explain how this phenomenon relates to the unaffected parts of their brain involved in sensory input?

outermost meninx covering of the brain; composed of tough fibrous connective tissue

innermost meninx covering the brain; delicate and highly vascular

structures instrumental in returning cerebrospinal fluid to the venous blood in the dural venous sinuses

structure that produces the cerebrospinal fluid

middle menix; like a cobweb in structure

its outer layer forms the periosteum of the skull

a dural fold that attaches the cerebrum to the crista galli of the skull

a dural fold separating the cerebrum from the cerebellum
