Just above the medulla are
the pons
and cerebellum. The pons relays information between higher regions of the brain and the cerebellum, which processes sensory information and helps coordinate movement. The next segment, the midbrain, is primarily responsible for eye movement.
What structure helps relay information from higher brain regions to the cerebellum?
Pons
: Found in the brainstem, the pons connects the medulla oblongata and the thalamus. It is composed of tracts responsible for relaying impulses from the motor cortex to the cerebellum, medulla, and thalamus.
What type of neurons convey information about the environment from the sense organs to the brain?
Sensory receptors
send messages along sensory nerves to the spinal chord, then up to the brain.
Which part of the brain is involved in autonomic function?
The hypothalamus
is the key brain site for central control of the autonomic nervous system, and the paraventricular nucleus is the key hypothalamic site for this control.
Which subdivision of the nervous system helped calm down and restore?
The autonomic nervous system
plays an important role in the human body, controlling many of the body’s automatic processes. This system also helps prepare the body to cope with stress and threats, as well as returning the body to a resting state afterward.
What part of the brain is referred to as the seat of higher mental functioning?
frontal
. this region of the brain contains the seat of higher mental functioning, including thinking.
Which of the following structures or areas of the brain is most active during decision making?
The Prefrontal Cortex (PFC) and hippocampus
are the most critical parts of the human brain for decision making. The decision-making process contains four steps.
What is the site of communication between neurons?
Neurons communicate at structures called
synapses
in a process called synaptic transmission. The synapse consists of the two neurons, one of which is sending information to the other.
What is nervous system with diagram?
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.
What does the brain do as soon as it receives the information?
After processing its many sensory inputs,the brain
initiates motor outputs (coordinated mechanical responses)
that are appropriate to the sensory input it receives. The spinal cord then carries this motor information from the brain through the PNS to various locations in the body (such as muscles and glands).
What part of the brain is the boss of the autonomic nervous system?
The hypothalamus
functions in: a) coordinating movement. b) regulating the autonomic nervous system.
What happens if the autonomic nervous system is damaged?
Autonomic neuropathy occurs when the
nerves that control involuntary bodily functions are damaged
. It can affect blood pressure, temperature control, digestion, bladder function and even sexual function.
How do you heal the autonomic nervous system?
- taking medication to help stabilize blood pressure;
- taking medication to control other symptoms, such as intolerance to hot temperatures, digestion issues, and bladder function;
- consuming fluids that are fortified with electrolytes;
- getting regular exercise; and.
What is an example of a parasympathetic response?
Examples of parasympathetic responses
Salivation
: As part of its rest-and-digest function, the PSNS stimulates production of saliva, which contains enzymes to help your food digest. Lacrimation: Lacrimation is a fancy word for making tears. Tears keep your eyes lubricated, preserving their delicate tissues.
Which branch of the autonomic nervous system mobilizes the body during extreme situations?
The sympathetic division
mobilizes the body during extreme situations such as fear, exercise, or rage.
Which of the following is a parasympathetic response?
Body functions stimulated by the parasympathetic nervous system (PSNS) include
sexual arousal, salivation, lacrimation, urination, digestion, and defecation
.
