What is the medial view of the brain?
In addition, there are four possible views of the brain: lateral, medial, dorsal, and ventral. Lateral is from the side; medial is towards the midline (often from a sagittal section); dorsal is looking from above; and ventral is looking from below. Brain Stem: pons, medulla, spinal cord.
What is the anatomical position of the cerebrum?
The cerebrum is located within the bony cranium. It extends from the frontal bone anteriorly to the occipital bone posteriorly. Within the skull, the cerebrum fills the anterior and middle cranial fossae, and is located above the tentorium cerebelli inferoposteriorly.
What are the different views of the brain called?
Viewing the brain in two dimensions These are typically viewed in three different planes: the sagittal, coronal, or axial planes.
What is medial and lateral in anatomy?
A lateral orientation is a position away from the midline of the body. For instance, the arms are lateral to the chest, and the ears are lateral to the head. A medial orientation is a position toward the midline of the body. An example of medial orientation is the eyes, which are medial to the ears on the head.
What is cerebral orientation?
Orientation is a function of the mind involving awareness of three dimensions: time, place and person. Problems with orientation lead to disorientation, and can be due to various conditions, from delirium to intoxication. Typically, disorientation is first in time, then in place and finally in person.
What are the midline structures of the brain?
Abstract. The development and aging of four brain midline structures–the pituitary gland, pons, cerebellar vermis, and corpus callosum–were studied. The dimensions and area of these structures were measured by means of midsagittal magnetic resonance imaging.
What is lateral view of brain?
The lateral view of the brain shows the three major parts of the brain: cerebrum, cerebellum and brainstem. A lateral view of the cerebrum is the best perspective to appreciate the lobes of the hemispheres.
What is ventral view of brain?
directional term that refers to the front. When used in reference to the nervous system, ventral refers to the front when discussing the spinal cord. However, above the junction of the midbrain and diencephalon, ventral refers instead to the lower or inferior portion of the brain.
What are the three layers of the cerebrum?
Your brain and spinal cord are protected and supported by three meningeal layers. These membrane layers are the dura mater, arachnoid mater and pia mater. The layers plus cerebrospinal fluid keep your brain tissue from jostling against your skull, as well as other functions.
What are the 4 lobes of the cerebrum and their functions?
The four lobes include the occipital, temporal, frontal, and parietal lobes. Each lobe is responsible for a specific task. The frontal lobe functions in solving problems, controlling body movements, sentence formation, and personality traits. The occipital lobe functions in processing visual images.
What is lateral and medial view?
What side is medial?
Medial – toward the midline of the body (example, the middle toe is located at the medial side of the foot). Lateral – away from the midline of the body (example, the little toe is located at the lateral side of the foot).
What is medial view in anatomy?
Medial means toward the middle or center. It is the opposite of lateral. The term is used to describe general positions of body parts. For example, the chest is medial to the arm.
What does midline shift of brain mean?
Midline shift refers to a shift (displacement) of brain tissue across the centre line of the brain. It may occur following traumatic brain injury in association with raised intracranial pressure or an intracranial haematoma which can push the brain towards one side causing midline shift.
What does midline shift indicate?
Shift of midline intracranial structures helps diagnosing intracranial lesions, especially traumatic brain injury, stroke, brain tumor, and abscess. Being a sign of increased intracranial pressure, MLS is also an indicator of reduced brain perfusion caused by an intracranial mass or mass effect.
What is coronal view of brain?
A coronal section is one that separates the brain into anterior and posterior halves. The coronal section shown in Figure 19a occurs approximately halfway between these two poles, and helps to show the placement of some of the major internal structures of the brain that will be referred to elsewhere.
What is dorsal view?
On a human body, dorsal (i.e., posterior) refers to the back portion of the body, whereas ventral (i.e., anterior) refers to the front part of the body.
