Anatomy and Pathology Flashcards
Bump in the back of head
Occiput
Where is CSF made?
In the choroid plexus located in the floor of the 3rd and 4th ventricle
Subdural Hematoma
Venous bleed caused by ruptured veins between the dura mater and the arachnoid mater
Caused by blow to frontal or occipital bone
Glioma-Astrocytoma
Most common brain tumour
Usually near outside of brain
compromises the blood brain barrier
Metastatic Carcinoma
Brain tumour that has metastasized from a primary tumour
Cerebrovascular Accident
Acute Ischemic Stroke: caused by loss of blood supply to a localized portion of the brain
Hemorrhagic Stroke: ruptured blood vessel in the brain
Body Planes
Sagittal
Transverse
Coronal
TIA
Transient Ischemic Attack: temp loss of neurologic functions that resolves within 24hrs
Usually happens before stroke
Meninges
Pia Mater: inner
Arachnoid Mater: middle
Dura Mater: outer
Cerebral Contusion
Bruising of the brain caused by blunt trauma
Lobes of the Brain
Frontal
Occipital
Temporal
Parietal
Membranes: Mediastinum
Parietal Pericardium: lines the mediastinum
Visceral Pericardium: lines the heart
Spina Bifida
Incomplete closure of the vertebral column
- Spina Bifida Occulta: fused, but there is a small opening-no visible abnormalities or mental deficits
- Spina Bifida Meningocele: meninges sticking out
- Spina Bifida Myelocele: spinal cord and meninges sticking out VERY SERIOUS
Membranes: Abdominopelvic Cavity
Parietal Peritoneum: lines the peritoneal cavity
Visceral Peritoneum: lines the organs
Types of Membranes
Epithelial: serous, mucous, cutaneous
Connective tissue membranes
