|
Where is the cerebrum and what does it do? |
The location of conscious thought and the origin of complex intellectual functions |
|
|
What are the 4 loves of the cerebrum? |
Frontal, parietal, occipital, temporal |
|
|
Where is the precentral gyrus and what does it do? |
Primary motor cortex located just anterior to the central suculus ( blue) |
|
|
Where is the central sulcus and what does it do? |
It separates frontal and parietal lobes and is made of a shallow depression |
|
|
What is the difference between a sulcus, a gyrus, and a fissure |
1. A gyrus is a fold of brain tissue 2. A sulcus is a shallow depression between gyri 3. A fissure is a groove deeper than a sulcus |
|
|
Where is the post central gyrus and what does it do? |
The orange gyrus just behind the central sulcus. It controls somatosensory interpretation from sensory neurons in joints and tendons. |
|
|
Where is the corpus callosum and what does it do? |
A major tract that links left and right hemispheres of the brain. |
|
|
Where is the lateral sulcus and what does it do? |
A deep groove that separates the frontal and parietal lobes from the temporal lobe |
|
|
Where is the longitudinal fissure and what does it do? |
A narrow, deep, cleft that separates the hemispheres. |
|
|
Where is the cerebellum and what does it do? |
Produces fine control over muscular actions and stores memories of movement patterns |
|
|
Where is the cerebellar hemispheres and what does it do? |
The cerebellum has a right and left hemisphere (like the cerebrum), but each has an anterior and posterior lobe |
|
|
Where is the cerebellar cortex and what does it do? |
Like the brain, the cerebellum has an outer layer of grey matter (called the cerebellar cortex) and an inner layer of white matter |
|
|
Where is the arbor vitae and what does it do? |
Like the brain, the cerebellum had an inner layer of white matter called the arbor vitae |
|
|
Where is the diencephalon and what does it do? |
Sandwiched between the interior regions of the cerebral hemispheres, the diencephalon provides relay centers for some sensory and motor pathways and controls visceral activities. |
|
|
What are the key structures of the diencephalon? |
1. Epithalamus 2. Thalamus 3. Hypothalamus |
|
|
Where is the fornix and what does it do? |
Major output tract of the hippocampus |
|
|
Where is the epithalamus and what does it do? |
Houses the pineal gland which regulates melatonin and circadian rhythm |
|
|
Where is the thalamus and what does it do? |
Connected by the interthalamic adhesion, the thalamus covers the 3rd venticle and relays sensory info while letting the cerebrum know where it came from |
|
|
Where is the hypothalamus and what does it do? |
Under the anterior region of the diencephalon, the hypothalamus controls the autonomic nervous system, endocrine system, regulates body temp, controls emotional behavior, controls food intake, controls water intake, regulates circadian rhythm |
|
|
Where is the infundibulumm and what does it do? |
A stalk that extends from the hypothalamus and connects the pituitary gland |
|
|
Where is the pituitary gland and what does it do? |
|
|
|
Where is the mamillary body and what does it do? |
Part of the hypothalamus, the mamillary body detects senstaions related to olfaction and controls swallowing |
|
|
Where is the midbrain and what does it do? |
The superior portion of the brain stem that houses other important structures like the mamillary bodies and the cerebral aqueduct. It also houses the nuclei of the occulomotor and trochlear nerves. |
|
|
Where is the tectal plate and what does it do? |
Sensory nuclei of the midbrain divided into superior and inferior colliculi. These nuclei are the relay stations in the processing pathway for visual and auditory sensations. |
|
|
Where is the superior colliculi and what does it do? |
The superior nuclei of the tectal plate located on the posterior side of the midvrain just above the cerebellum. Called the visual reflex center because it visually tracts moving objects and controls reflexes like Turing the eyes and head in response to a visual stimulus. |
|
|
Where is the inferior colliculi and what does it do? |
Located on the posterior side of the midbrain just above the cerebellum, the inferior colliculi is the auditory reflex center and controls refexive turning of the head and eyes in response to sound. |
|
|
Where are the pons and what do they do? |
Located on the brain stem in between the midbrain and the medulla oblongata. Houses motor and sensory tracts that connect through it. It is also the location of multiple Cranial nerves - trigeminal, abducens, facial, vestibulocochlear. |
|
|
Where is the medulla oblongata and what does it do? |
The most inferior part of the brain stem. All communication between the brain and spinal cord passed through the medulla oblongata. |
