Study Notes
Encephalon - Animal Body Function VII
- Encephalon controls the body's organs, regulating, coordinating and integrating the nervous system.
- Its abilities are reflected in its anatomical features.
Brainstem
- Composed of three parts: medulla oblongata, pons, and midbrain.
- Consists of grey and white matter.
- It contains various nuclei of grey matter.
- White mater includes association fibers, commissural fibers and projection fibers.
Brain Functions
- Control of the organs of the body
- Responsible for regulation, co-ordination and integration of the nervous system.
- Its abilities are similar to its morphological features.
Localization
- Housed within the neurocranium (skull).
- Enclosed within the frontal, parietal, occipital, temporal, ethmoid and sphenoid bones.
- Specifically within the cranial cavity.
