How many bones make up the skull?
A region of the cerebral cortex defined by cytoarchitecture
What is Brodmann’s area?
An area responsible for processing intellectual and emotional events
What is the prefrontal cortex?
Is also referred to as cerebrum and is the largest part of the brain
What is the telencephalon?
The system of motor neurons that innervate the smooth muscle, cardiac muscle and glands of the body
The autonomic nervous system
Skull-Periosteal dura mater - Meningeal dura mater - Arachnoid mater - Pia mater - Telencephalon
What are the layers surgeons need to drill through to reach the brain?
They are loosely related to the cranial bones
What are the lobes of the brain related to?
An area responsible for memory, learning, motivation and emotion as well as endocrine and autonomic function
What is the limbic lobe?
The thin outer layer of the Cerebrum
What is the Cortex?
3: Sensory, Motor and Inter-
How many different types of neurons are present in the spinal cord?
The originally only anatomical classification of the brain
What are the frontal, parietal, occipital and temporal lobes? (Limbic lobe added later)
A mass of nuclei located deep and medially within the temporal lobes
What is the Amygdalla?
The area responsible for conscious perception of sound
What is the primary auditory cortex?
A fibre that passes from one side of the brain to the other to connect similar areas
What is a commissure?
These are the cell types of the brain
What are neuroglia and neurons?
4: Metopic, Coronal, Sagittal and Lambdoid
How many sutures does the skull have?
Motor, Sensory and Association
What are types of cortical areas?
The area responsible for the execution of skilled voluntary movements
What is the primary motor cortex?
Indication of the areas and amounts of neurons of the primary motor cortex
What is the motor homunculus?
Non-neuronal cells that outnumber neurons 50:1 (in the brain)
Glial cells
The 5 devisions of the brain that correspond to their embryonic vesicles
What are the Telencephalon, Diencephalon, Mesencephalon, Metencephalon and Myelencephalon
Found in both hemispheres but is called Wernicke’s area in the dominant one
What is the auditory association area?
The area responsible for the formulation of the motor components of speech
What is the Brocca’s area?
The primary receiving area of somatosensory information
What is the postcentral gyrus?
It’s cell body lies in the CNS and it’s axon is in a peripheral autonomic ganglion
What is the preganglionic neuron?
