Where is the hyoid bone?
It is the U shaped bone that is inferior to the mandible
What are the articulating bones of the temporomandibular joint?
Temporal bone, and the mandible
What is the function of the corpus callosum?
To connect the left and right hemispheres of the brain
What are the functions of the thalamus?
To process sensory information and direct it to the proper part of the cerebrum
What are the functions of the hypothalamus?
It is the hormone and autonomic control center of the brain
What is the function of the epithalamus?
It contains the pineal gland (secretes hormones from the hypothalamus)
What is the function of the superior colliculus?
To process visual reflexes
What is the function of the inferior colliculus?
To process auditory reflexes
What are the functions of the pons?
It acts as the relay center between the forebrain and cerebellum; it also regulates sleep
What are the functions of the cerebellum?
Motor learning, balance, equilibrium
What is the function of the arbor vitae?
It is a visual description of how grey and white matter are organized in the cerebellum
What are the functions of the medulla oblongata?
It has several autonomic nervous system functions including:
- respiration
- cardiac function
- vasodilation (widening of blood vessels)
- vomiting
-swallowing
What is the function of the pituitary gland?
To secrete hormones that affect functions of the entire body
What is the function of the ventricles?
They are spaces in the brain that contain and create cerebrospinal fluid
What are the functions of the frontal lobe?
Executive function, attention, primary motor cortex, and language
What is the function of the prefrontal cortex?
It is in the frontal lobe and it controls executive functions
What are the functions of the parietal lobes?
To integrate sensory information such as touch, pressure, taste, and pain
What is the function of the temporal lobe?
The primary visual cortex that contains and processes visual information
What are the functions of the temporal lobes?
To process sensory information for hearing and memory formation
What does gyrus mean?
A single ridge of a cortex in the cerebrum
What does gyri mean?
It is the term for multiple ridges in the cerebrum
What is located in the precentral gyrus?
The primary motor cortex
What is located in the postcentral gyrus?
The primary somatosensory cortex
What does sulcus mean?
A singular depression of the cortex
What does sulci mean?
Multiple depressions of the cerebral cortex
Where is the longitudinal fissure located?
Between the left and right hemispheres
Where is the central sulcus located?
Between the frontal and parietal lobes
Where is the lateral sulcus located?
Between temporal, frontal, and parietal lobes
Where is the parieto-occipital sulcus located?
Between the parietal lobes and the occipital lobes
Where is the transverse fissure located?
Between the cerebrum and cerebellum
What is the purpose for the cervical enlargement of the spinal cord?
For motor and sensory neurons to have space to go to/ from the upper extremities
What is the purpose for the lumbar enlargement of the spinal cord?
For motor and sensory neurons to have space to go to/ from the lower extremities
What is the purpose of the cauda equina of the spinal cord?
The “horse tail” of the nerve roots going down from L1- L2
What is the purpose of the conus medullaris on the spinal cord?
It is the tapered end of the spinal cord
What is the purpose for the filum terminale on the spinal cord?
It is the thin string of connective tissue going from the tip of the conus medullaris to the coccyx
What is in grey matter?
It is made up of cell bodies, along with unmyelinated axons, and dendrites
What is located in the dorsal horn?
Sensory neurons coming from the body here
What is located in the ventral horn?
The start of motor neurons going out to the rest of the body
What does white matter contain?
Myelinated axons
Where is the longitudinal fissure located?
It separates the left and right hemispheres
Where is the central sulcus located?
It separates the frontal and parietal lobes
Where is the lateral sulcus located?
It separates the frontal temporal and parietal lobes (aka the nike swoosh)
Where is the Parieto-occipital sulcus located?
It separated the parietal lobes from the occipital lobes
Where is the transverse fissure located?
It separates the cerebrum from the cerebellum
What does the fornix do?
It helps form memories
Where is the fornix located?
Under the corpus callosum
What is the fornix made out of?
White matter
What is the name for the ear canal?
External acoustic meatus
What are sutures?
Fibrous joints that connect cranial bones
What does the cribriform plate allow for?
The small holes allow for olfactory neurons to innervate the nasal cavity (allows for you to smell things from your nose)
