Which condition includes a sense perception that has no basis in external stimulation?

Ch 10 Vocabulary

A	B
hallucination	A sense perception that has no basis in external stimulation.
hemorrhagic stroke	Damage that occurs when a blood vessel in the brain leaks or ruptures.
hydrocephalus	Abnormally increased amount of cerebrospinal fluid within the brain.

Simply so, what is a sensory perception that has no basis in external stimulation?

hallucination. a sense perception that has no basis in external stimulation. catatonic behavior. marked by a lack of responsiveness, stupor and a tendency to remain in a fixed position.

Subsequently, question is, which condition is the inflammation of a nerve causing pain through the thigh and leg? Inflammation of the sciatic nerve that results in pain, burning, and tingling along the course of the affected sciatic nerve through the thigh, leg, and foot.

Similarly, it is asked, are sites in the sensory organs that receive external stimulation?

are sites in the sensory organs (eyes, ears, skin, nose, and taste buds) that receive external stimulation. also known a sensory neurons, these neurons emerge form snsory organs and the skin to carry the impulses frm the sensory organs toward the brain and spinal cord.

What suffix means sensation or feeling?

-esthesia. suffix meaning sensation, feeling.

Which part of the brain is responsible for the highest level of thought?

Cerebrum. Beneath the cerebral cortex is the cerebrum, which serves as the main thought and control center of the brain. It is the seat of higher-level thought like emotions and decision making (as opposed to lower-level thought like balance, movement, and reflexes).

What drug is also known as a tranquilizer?

Major tranquilizers, which are also known as antipsychotic agents, or neuroleptics, are so called because they are used to treat major states of mental disturbance in schizophrenics and other psychotic patients.

What term describes the space between two neurons?

the term that describes the space between two neurons or between a neuron and a receptor is. synapse. the protective covering over some nerve cells is the. myelin sheath. the root like structures of a nerve the receive impulses and conduct them to the cell body are the.

What is the absence of the normal sense of pain?

Congenital insensitivity to pain (CIP), also known as congenital analgesia, is one or more rare conditions in which a person cannot feel (and has never felt) physical pain.

What is the protective covering over some nerves?

A protective covering called the myelin sheath surrounds all the dendrites and the axon. The myelin sheath is a fatty layer that acts as a layer of insulation. This layer prevents the nerve signals of one neuron from interfering with that of another neuron.

Which term means inflammation of the brain?

The medical term that means inflammation of the brain is: Encephalitis. Yael is diagnosed with amyotrophic lateral sclerosis, which is: Progressive muscle atrophy caused by degeneration of motor neurons in the lateral columns of the spinal cord.

What term means abnormally increased spinal fluid in the brain?

1/2. Water on the brain: Known medically as "hydrocephalus", this is an abnormal buildup of cerebrospinal fluid (CSF) in the ventricles of the brain. The fluid is often under increased pressure and can compress and damage the brain.

Which condition is the bruising of brain tissue?

Cerebral contusion, Latin contusio cerebri, a form of traumatic brain injury, is a bruise of the brain tissue. Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries.

What is a bundle of nerve fibers located outside the central nervous system?

Anatomy and Physiology of the Nervous System

A	B
nerve	is a group or bundle of fibers located outside the central nervous system that connect the brain and spinal cord with various parts of the body
afferent neurons	carry impulses to the brain and spinal cord from the skin and sense organs.

What is the largest nerve in the body?

sciatic nerve

What is the process of the nervous system?

The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. The central nervous system (CNS) includes the nerves in the brain and spinal cord.

How does sensory information travel to the brain?

1) sensory neurons—receive impulses and carry them from the sense organs to the spinal cord or brain. 2) interneurons—connect sensory and motor neurons and interpret the impulse; only in the brain and spinal cord. An impulse travels along the neuron pathways as electrical charges move across each neural cell membrane.

How does the nervous system collect sensory input?

Afferent or sensory neurons collect stimuli received by receptors throughout the body, including the skin, eyes, ears, nose, tongue as well as pain and other receptors in the internal organs. Sensory information is transmitted to the central nervous system, which includes the brain and spinal cord.

What are the two basic functional units of the nervous system?

Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system. They transmit electrical signals, called nerve impulses. Glial cells provide support for neurons.

What sort of signals does the nervous system carry?

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring.

Where does the nervous system receive information?

Central nervous system It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.

How information is transmitted through the nervous system?

Your nervous system contains millions of nerve cells, called neurons. Neurons are highly specialised to transmit messages from one part of your body to another. Sensory neurons, which pass information about stimuli such as light, heat or chemicals from both inside and outside your body to your central nervous system.

What are the symptoms of a spinal infection?

The symptoms of a spinal infection include fever, chills, headache, neck stiffness, pain, wound redness and tenderness, and wound drainage. In some cases, patients may notice new weakness, numbness or tingling sensations in the arms and/or legs. The symptoms may be very severe, or they may be very subtle in some cases.

Is a condition characterized by poor muscle control?

A condition characterized by poor muscle control, spasticity, speech defects, and other neurologic deficiencies due to damage that affects the cerebrum. Damage to the brain that occurs when the blood flow to the brain is disrupted by a blockage of the blood supply; also known as a stroke.
