10 parts of the brain Flashcards
Largest part of the brain; divided into the right and left hemispheres; composed of the frontal, parietal, occipital, and temporal lobes
Cerebrum
Composed of the pons, midbrain, and the medulla oblongata
Brain Stem
Composed of the thalamus and the hypothalamus
Diencephalon
This structure means bridge; it helps regulate breathing rate and rhythym
Pons
Brain structure that protrudes from under the occipital lobe; concerned primarily with the coordination of skeletal muscle activity
Cerebellum
The precentral gyrus of this cerebral lobe is the major motor cortex; nerve impulses generate in the motor area control voluntary muscle activity
Frontal Lobe
Plays a key role in personality development, emotional and behavioral expression, and performance of high level thinking and learning tasks
Frontal Lobe
Cerebral lobe that contains the frontal eye fields; a motor homunculus lives here; controls motor speech (broca’s area)
Frontal Lobe
The central sulcus separates the frontal lobe from this lobe; the postcentral gyrus of this cerebral lobe is the primary somatosensory area
Parietal Lobe
A sensory homunculus lives here
Parietal Lobe
Cerebral lobe that contains the auditory (hearing) cortex and the olfactory (smelling) cortex
Temporal Lobe
Damage to this lobe causes cortical deafness
Temporal Lobe
Called the emotional brain
Limbic System
This widespread group of cells is concerned with the sleep-wake cycle and consciousness; signals passing from this structure to the cerebral cortex keep us awake
Reticular Formation
Cerebral lobe that is primarily concerned with vision; damage to this lobe causes cortical blindness
Occipital Lobe
Part of the diencephalon that controls the pituitary gland; also helps control the autonomic nervous system, water, balance, and body temperature
Hypothalamus
We first become aware of pain at this level of the diencephalon; doesn’t allow us to determine type of pain or where its coming from
Thalamus
Part of the diencephalon that acts as a relay and sorting station for most sensory fibers
Thalamus
Part of the brain stem that connects the brain to the spinal chord; crossing of the motor fibers occurs here; part of the brain stem that contains the emetic (vomit) center
Medulla Oblongata
Part of the brain stem called the vital center because it regulates processes such as blood pressure, heart rate, and respirations
Medulla Oblongata
Part of the brain stem that contains the vomiting center; Receives info from the chemoreceptor trigger zone
Medulla Oblongata
Bands of white matter that join the right and left cerebral hemispheres
Corpus Callosum
