Nervous System Flashcards
body’s central nervous system. Is the pathway for messages sent by the brain to the body and from the brain to the body
Spinal Cord (dorsal)
receives information from sensory systems. Coordinates voluntary movements by balance in speech
Cerebellum (dorsal)
controls movement of the right side of the body.
Left Cerebral Hemisphere (dorsal)
allows for an increase of cognitive ability. Folds or bumps in the brain. Separate brain regions. (Hills)
Gyrus (dorsal)
separates the parietal lobe from the frontal lobe. Increases the surface area making more functions possible. (Valleys)
Sulcus (dorsal)
space between the right and the left hemisphere. Not any function just a result of how the brain develops.
Longitudinal Fissure (dorsal)
controls movement of the left side of the body. Performs tasks that have to do with creativity and arts.
Right Cerebral Hemisphere (dorsal)
divides cerebrum from the cerebellum.
Transverse Fissure (dorsal)
secretes hormones into your bloodstream. Hormones can affect other organs and glands. Located between the hypothalamus and the pineal gland.
Pituitary Gland (ventral)
located in the eye. Takes visual information gathered from your eye and transmit it using a series of electrical impulses to parts of your brain.
Optic Nerve (ventral)
located in the forebrain of vertebrae that receives neural input about odors detected by cells in the nasal cavity.
Olfactory Bulb (ventral)
the largest part of the brain composed of right and left hemispheres. Higher functions like touch, vision, and hearing.
Cerebrum (ventral)
x shaped structure crossing the optic nerves. Crucial to function.
Optic Chiasm (ventral)
Regulates breathing, digestion, and swallowing. Respiration and circulating center. Located in the brainstem.
Medulla Oblongata (ventral)
Controls the body and communication among its parts. Brain, spinal cord, and sensory organs all have these
Nerves (ventral)
located in brainstem above the medulla oblongata. contain nuclei that relay signals from the forebrain to the cerebellum.
Pons (ventral)
integrate motor, sensory, and cognitive performances between the cerebral cortex on one side of the brain to the same region on the other side
Corpus Callosum (lateral)
structures within the brain that contain cerebrospinal fluid that provides cushioning for the brain while circulating nutrients and removing waste.
Lateral Ventricle (lateral)
relays motor and sensory signals to the cerebral cortex. Located just above the brainstem between the cerebral cortex.
Thalamus (lateral)
produces melatonin, which helps maintain circadian rhythm and regulate reproductive hormones. Located deep in the center of the brain.
Pineal gland (lateral)
upper layer receives visual signals from the retina of the eye while the lower layer processes multiple signals from various parts of the brain.
Superior Colliculus (lateral)
brings sensory and motor information to and from the cerebellum. Located deep in the cerebellum.
Arbor Vitae (lateral)
located in the brainstem. Protects the human brain from trauma and helps form the central canal, which runs the length of the spinal cord.
Fourth Ventricle (lateral)
motor movement like eye-movement, auditory, and visual processing. Located toward the base of your brain.
Midbrain (lateral)
