The nervous system consisting of all of the neurons and nerves that run through the body that are not contained in the brain or spinal cord is known as the __________.

a damage to the frontal lobe b inheritance of a mutated gene c an excess of dopamine d a lack of oxygen at childbirth

Explanation / Answer

Ans 1: Schizophrenia Disorder of the brain is caused by inheritance of a mutated gene. The experience of pervasive mental changes, such as the inability to think clearly, perceive correvtly, and manage intense emotions. Usually includes hallucinations and delusions. Sympotoms that are a mixture of schizophrenia and the mood disorders experiencing one of the following: delusions, hallucinations, disorganized speech, disorganized behavior, or negative symptoms. Cause: High genetic liability to mood disorders and schizophrenia. Onset is late adolescence or early adulthood.

Ans 2: Myelin sheath: lipid layer that covers the axon and insulates the axon to speed up transmission of the signal.

Ans 3: Having problem in storing away new memories, the damage is most likely in the hippocampus area of the brain. The hippocampus is a small organ located within the brain's medial temporal lobe and forms an important part of the limbic system, the region that regulates emotions. The hippocampus is associated mainly with memory, in particular long-term memory. The organ also plays an important role in spatial navigation. Damage to the hippocampus can lead to loss of memory and difficulty in establishing new memories.

Ans 4: Sympathetic nervous system: To defend the body against attack. Catabolic (breaks down the body). The brain, muscles, the insulin pancreas and the thyroid and adrenal glands Raises blood pressure and blood sugar, and increases heat production Sympathetic nervous system (SNS) - the SNS triggers what is commonly known as the "fight or flight" response:
* sympathetic neurons are generally considered to belong to the peripheral nervous system, although some of the sympathetic neurons are located in the CNS (central nervous system)
* sympathetic neurons of the CNS (spinal cord) interact with peripheral sympathetic neurons through a series of sympathetic nerve cells bodies known as ganglia

Ans 5: Synapse (or synaptic gap or cleft)

-Space between the terminal buttons of one neuron and the dendrites of the next neuron
-terminal buttons and dendrites never touch

Ans 6: Pituitary gland. Also known as the master gland because it exerts control over all of the other glands of the endocrine system. Despite its importance the pituitary gland is no larger than a small pea. The Pituitary gland is made up of two separate glands: the Anterior lobe which is an outgrowth of the pharynx, and the Posterior lobe which is an outgrowth of the brain composed of neural (nerve) tissue

The Endocrine system (along with the nervous system) controls and regulates the complex activities of the body. The Endocrine system regulates the activities of the body by secreting complex chemical substances (hormones) into the blood stream. These secretions come from a variety of glands which control various organs of the body. Its key functions are:

Ans 7: b.

The occipital lobe is one of the four major lobes of the cerebral cortex in the brainof mammals. The occipital lobe is the visual processing center of the mammalianbrain containing most of the anatomical region of the visual cortex.

Ans 8: a.

The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response. This component of the autonomic nervous system utilizes and activates the release of norepinephrine in the reaction.

Ans 9: d.

Sensory neurons carry electrical signals (impulses) from receptors or sense organs to the CNS. Sensory neurons are also called afferentneurons. The cell body of sensory neurons is outside the CNS in ganglia.

Ans 10: when a person has damage to the Wernicke's area. it causes difficulty comprehending the language of others. most of the time, damage to this area does not result in the patient having problems initiating and planning speech whereas patients with Broca's have trouble with the expressive aspects of communication and are confluent, patients with Wenicke's aphasia have problems comprehending language and their speech tends to be fluent

Ans 11: They are thus known as the "supporting cells" of the nervous system. The four main functions of glial cellsare: to surround neurons and hold them in place, to supply nutrients and oxygen to neurons, to insulate one neuron from another, and to destroy and remove the carcasses of dead neurons (clean up).

Ans 12: b

When acetylcholine is released from an axon terminal, it moves across the synaptic cleft to bind to a receptor on the other side of the synapse (on the post-synaptic membrane). In the peripheral nervous system, acetylcholine is located at the "neuromuscular junction" where it acts to control muscular contraction. memory, attention, and arousal

Ans 13: Brain Lateralization is a complex and ongoing process by which differing regions of the brain take over the functioning of specific behaviors and cognitive skills.Lateralization literally means that certain functions are located (in part or total) on one side of the brain.

Ans 14: Endocrine system is made up of numerous glands that are located throughout the body. These glands secrete various chemicals called hormones, that affect organs, muscles, and other glands in the body.

Ans 15: b

Ans 16: c

In the split-brain operation, the corpus callosum is severed, which is the primary communication pathway between the two hemispheres.

Ans 17: c

the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron (the tiny gap at this junction is called the synaptic gap or cleft)

Ans 18: a

The brain mapping technique that injects dyes into the blood vessels of the head to obtain dynamic information about the brain is called angiograms. An angiogram is an X-ray test that uses a special dye and camera (fluoroscopy) to take pictures of the blood flow in an artery (such as the aorta) or a vein (such as the vena cava). An angiogram can be used to look at the arteries or veins in the head, arms, legs, chest, back, or belly

Ans 19: c

This gland is often called the 'master gland' as it controls many other glands in the endocrine system.

Ans 20: b.

Peripheral nervous System PNS: all nerves and neurons that are not contained in the brain and spinal cord but that run through the body itself, divided into Somatic and Autonomic nervous sytem
