CNS Flashcards
Where is the brain localized?
Inside the cranial cavity
Where is the spinal cord localized?
In the Vertebral canal of the vertebral column
What is the brain and spinal cord protected by?
The menings= membranes
what supports the face like nerves, sensory organs, cavities of the digestive and respiratory systems and mimic muscles and muscles of mastication?
The skull
the neurocranium and the viscerocranium or facial skeleton, what is it?
The skulls two parts
What are the eight bones in the neurocranium called?
Singel bones:
Frontal bone, Occipital bone, Sphenoid bone, Ethnoid bone.
Paired bones:
Parietal bones, Temporal bones
Where is the Occipital bone located and what can you find in that area?
In the posterior part and the floor of the neurocranium. You can find the foramen magnum and the medulla oblongata
Where is the Sphenoid bone located and what is its shape?
Its located in the middle of the cranial floor and has bat shaped body with greater and lesser wings.
where can the Stella Murcia be found?
in the sphenoid bone
what bone is located in the anterior part of the base of the cranium?
The ethmoid bone
What can be found besides the ethnoid bone?
The cribriform plate and the crista galli
Which bone contributes to the roof of the nasal cavity formation, with the perpendicular plate and the superior and middle conchae?
The ethmoid
The vomer bone is located in..?
the inferior part of the nasal cavity.
The frontal bone is located?
in the anterior part of the neurocranium
What comes right behind the frontal bone?
coronal suture
what are the two bones celled that are divided by the sagittal suture?
Parietal bones
What is the suture called that continues from the sagittal suture in the posterior part of the skull?
Lambdoid suture
Temporal bones are located where?
the lateral side of the cranium
What is the suture called that circles the temporal bones?
Squamous suture
what’s the suture called that is between the temporal and occipital bone and meets the lambdiod suture?
occipitomastiod suture
anterior cranial fossa is formed by?
frontal, the ethmoid and the sphenoid bones and contains the two frontal lobes of the cerebrum
middle cranial fossa is formed by?
the temporal and the sphenoid bones and hosts the temporal lobes
posterior cranial fossa is formed by?
occipital and the petrous parts of the temporal bones. It hosts the cerebellum and contains the foramen magnum where the brainstem lodges.
how many bones does the viscerocranium or facial skeleton consist of and how many are single or paired?
14 bones, two of them single and six paired bones
