What are the vast majority of neurons in the brain classified as?
Multipolar neurons are defined as having three or more processes that extend out from the cell body. They comprise of more than 99% of the neurons in humans, and are the major neuron type found in the CNS and the efferent division of the PNS.
What was Phineas Gage most strikingly debilitated by?
Following massive damage to his frontal lobes, Phineas Gage was most strikingly debilitated by: A. irritability.
What does the autonomic nervous system most directly control?
The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal. This system is the primary mechanism in control of the fight-or-flight response.
Which region of the brain appears to have the oldest developmental history?
Which region of the brain appears to have the oldest evolutionary history? cerebellum.
What are the stages of brain development?
4 stages of cognitive development
- Sensorimotor Stage: Birth through about 2 years.
- Preoperational Stage: Ages 2 through 7.
- Concrete Operational Stage: Ages 7 through 11.
- Formal Operational Stage: Ages 11 and older.
Is limbic system part of old brain?
The limbic system Many regions fundamental to mood are buried deep in the most primordial parts of the brain; that is, they are thought to have been among the first to develop in the human species. The limbic system is the major primordial brain network underpinning mood.
Where are most neurons located in the nervous system?
The vast majority of neurons in the body’s information system are _____. This part of the peripheral nervous system controls the voluntary movements of the skeletal muscles. This part of the nervous system helps one to conserve energy as it calms one down after a stressful event.
How is information carried to the central nervous system?
Information from the peripheral nervous system is carried to the central nervous system by neural “cables” called _____. In addition to its role in learning and memory, acetylcholine also controls _____. In terms of their length of effect, _____ messages last far longer than neural messages.
What kind of neurons are in the spinal cord?
Neurons that allow the brain and spinal cord to communicate internally are known as _____. The peripheral nervous system consists of sensory and _____ neurons. In terms of their length of effect, endocrine messages last far longer than _____ messages.
Which is an important part of the endocrine system?
Endocrine glands that play an important role in helping us respond to stress are the: adrenal glands. The vast majority of neurons in the body’s information system are: interneurons. Bladder contractions are controlled by the _____. autonomic nervous system
