EZ-Anat Ch. 11
Barron's E-Z Anatomy and Physiology Chapter 11 review
| Question | Answer |
|---|---|
| The brain and spinal cord are components of the: | central nervous system |
| The axons and dendrites extend from the spinal cord to the muscles and glands and form: | nerves |
| The spinal cord passes downward from the brain and extends through a bony tunnel found in: | vertebrae |
| The spinal cord is continuous with the: | brain (medulla oblongata) |
| The three membranes surrounding and protecting the spinal cord are called: | meninges |
| The outermost membrane surrounding the spinal cord is the: | dura mater |
| The inner membrane surrounding the spinal cord and having many blood vessels is the: | pia mater |
| Clear, watery fluid is found in the central canal of the spinal cord and is called: | cerebrospinal fluid |
| Injury to the ventral root of the spinal cord results in a condition called: | paralysis |
| The spinal cord serves as a coordinating center for the: | reflex arc |
| The brain receives impulses from the spinal cord as well as from 12 pairs of: | cranial nerves |
| The brain is composed of two major: | hemispheres |
| The brain consumes about one quarter of the body's: | oxygen |
| The outer portion of the brain is mainly composed of: | gray matter |
| The numerous convolutions of the brain are called: | gyri |
| The anterior portion of each cerebral hemisphere is occupied by a lobe called the: | frontal lobe |
| At the posterior portion of the cerebral hemispheres is a lobe called the: | occipital lobe |
| The region of the frontal lobe concerned with motor function for speech is: | Broca's area |
| The sense of smell is located deep within a portion of the brain known as the: | cerebrum |
| The interpretation of visual patterns occurs in the lobe of the brain known as the: | occipital lobe |
| The cavities of the brain are called the: | ventricles |
| The brain region lying posterior to the medulla and serving as a coordinating center for motor activity is the: | cerebellum |
| The cerebellum is composed of two lateral: | hemispheres |
| Because it is a reflex center for coordinating muscle activity, the cerebellum helps smooth gait and maintain: | posture |
| The nucleus of the diencephalon relaying sensory impules into the cerebral cortex is the: | thalamus |
| The nucleus of the diencephalon producing some hormones stored to be released by the pituitary gland is the: | hypothalamus |
| Emotional experiences such as fear, anger, pleasure, and sorrow are regulated in a ring of tissue at the edge of the brain stem called the: | limbic system |
| The rounded bulge in the brain stem separating the midbrain from the medulla is the: | pons |
| The swollen stem of the brain connecting the spinal cord to the remainder of the brain is the: | medulla oblongata |
| In the cerebrum of the brain, impulses cross over to opposite sides of the brain via the: | decussation of pyramids |
| The network of nerve fibers in the medulla responsible for activating the cerebral cortex is the: | reticular formation |
| The sensory somatic system is composed of spinal nerves and: | cranial nerves |
| The human body has spinal nerves numbering: | 31 pairs |
| The cranial nerve associated with smell is the: | olfactory nerve |
| The cranial nerve with sensory and motor functions controlling the heart, blood vessels, and organs of the viscera is the: | vagus nerve |
| The spinal nerves communicate impulses between various parts of the body and the: | spinal cord |
| Bodies where spinal nerves combine temporarily before passing to the destination points are known as: | plexuses |
| The autonomic nervous system operates in a manner that is: | involuntary |
