Nervous System Flashcards
The______transmits signals between the brain and the rest of the body, including internal organs. In this way, the _______ activity controls the ability to move, breathe, see, think, and more.
nervous system
brain and spinal cord
Central Nervous System
cranial nerves and spinal nerves that carry information in and out of the CNS.
which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons.
Peripheral Nervous System
conveys impulses to the central nervous system from sensory receptors located in various parts of the body.
Sensory (afferent)
carries impulses from the CNS to effector organs, muscles, and glands. These impulses activate muscles and glands.
Motor (efferent)
allows us to consciously, or voluntarily, control our skeletal muscles.
Somatic Nervous System
regulates events that are automatic, or involuntary, such as the activity of smooth and cardiac muscles and glands.
Autonomic Nervous System
responds to stress and is responsible for the increase of your heartbeat and blood pressure, among other physiological changes, along with the sense of excitement you may feel due to the increase of adrenaline in your system.
Sympathetic
is evident when you rest or feel relaxed and is responsible for such things as the constriction of the pupil, the slowing of the heart, the dilation of the blood vessels, and the stimulation of the digestive and urinary systems.
Parasympathetic
It receives information from our senses and controls our thoughts and movements.
Brain
What are the parts of the brain
Diencephalon/interbrain
Brain Stem
Cerebellum
Cerebrum
Left Hemisphere
Right Hemisphere
relay station for sensory impulses passing upward to the sensory cortex.
Thalamus
Referred as the Main Input center, as it regulates information form our body before sending to our cerebral cortex.
o plays a role in sleep, wakefulness, consciousness, learning and memory.
Thalamus
All information from your body’s senses (except smell) must be processed through your ___ before being sent to your brain’s cerebral cortex for interpretation.
Thalamus
plays a role in sleep, wakefulness, consciousness, learning and memory.
