Introduction to Neuroanatomy Flashcards
Name the bony structure surrounding the brain and the spinal cord?
Brain- Skull
Spnal Cord- Vertebral Canal
Name the type of muscle innervated by fibers of the somatic nervous system?
Striated muscle
How many angular degrees separate the horizontal plane from the coronal plane
90º
The coronal plane is a cross section of the horizontal plane
Name the three major embryological subdivision of the brain
Prosencephalon, Rhombencephelon, Mesencephalon
Name the minor subdivisions of the hindbrain and of the forebrain
- The Prosencephalon(forebrain) consists of the telencephalon and diencephalon
- The Rombencephalon(hindbrain) consists of the metencephalon and myelencephalon
Name the ventricular cavities of each subdivision of the brain
Name the structural and functional unit of the nervous system
The structural and functional unit of the nervous system is the neuron
List the twelve cranial nerves by name and number
CN I - Olfactory
CN II - Optic
CN III - Oculomotor
CN IV- Trochlear
CN V- Trigeminal
CN VI- Abducents
CN VII- Facial
CN VIII -Vestibulocochlear
CN IX- glossopharyngeal
CN X- Vagus
CN XI- Accessory
CN XII- Hypoglossal
Name the components of the brainstem
Mesencephalon- midbrain
Meylencephalon- medulla oblongata
Metencephalon- pons
Name the lobes of the Cortex
Name the borders of each of the lobes of the cortex
The frontal lobe lies rostral to the central sulcus and superior to the lateral fissure.
The occipital lobe lies behind an imaginary line drawn from the parieto-occipital sulcus to the preoccipital notch.
The temporal lobe lies below the lateral fissure and an imaginary extension drawn caudally to the occipital lobe.
The parietal lobe occupies the remainder of the lateral surface.
Define ipsilateral
the axon courses and/or terminates on the same side as its cell body
Define contralateral
the axon courses and/ or terminates on the side opposite its cell body
Define bilateral
the axon divides and courses and or terminates on both sides
Define decussation
fibers ascend/descend as they cross
Define commissure
fibers pass directly from one side to the other
