The Brain
This lobe of the brain is responsible for the awareness of sensations such as pain, pressure, temperature, touch, and position-conscious proprioception
What is the parietal lobe?
This part of the brain divides the cerebrum into left and right halves known as cerebral hemispheres
What is the longitudinal fissure?
Where sensory fibers enter the spinal cord
What is the dorsal (posterior) root?
This nerve a) transmits impulses from receptors in skin and mucous membranes of head, face, mouth/tongue; b) transmits impulses from proprioceptive sensory axons from extrinsic eye muscles; and c) stimulates muscles of mastication for control of chewing movements
What is the trigeminal nerve?
This part of the brain assists with voluntary skeletal muscle movement by controlling any associated subconscious movements which accompany voluntary activity
What are basal nuclei?
This is a cluster of neuronal cell bodies within the central nervous system
What are nuclei?
A spinal nerve that divides into branches
What is a ramus?
This nerve stimulates the contraction of muscles of the pharynx for swallowing, as well as secretes saliva from the parotid gland
What is the glossopharyngeal nerve?
This part of the brain a) helps maintain waking state, b) controls emotions of rage and aggression, and c) detects changes in the internal environment (temperature via thermoreceptors or ECF osmotic pressure via osmoreceptors)
What is the hypothalamus?
These are convolutions in the brain that result during embryonic development ... occurs when grey matter (of cortex) develops faster than white matter, and folds upon itself
What are gyri?
The meningeal branch is a branching of spinal nerves that re-enters the vertebral cavity through which opening?
What is intervertebral foramen?
This nerve has sensory functions of a) transmitting impulses from taste receptors on the posterior 1/3 of the tongue and b) transmitting impulses from baroreceptors and chemoreceptors in the carotid sinus
What is the glossopharyngeal nerve?
One of the functions of this part of the brain is to act as a relay station for sensory tracts
What is the thalamus?
These are the deepest grooves between folds (gyri) of cerebral cortex
What are fissures?
This nerve arises from the lumbar plexus and supplies the anterolateral abdominal wall, the external genitals, and part of the lower limbs
What is the femoral nerve?
This nerve stimulates the contraction of the muscles of the tongue for speech and swallowing
What is the hypoglossal nerve?
This part of the brain acts subconsciously to produce skilled and controlled muscle movements, as well as maintains posture and balance
What is the cerebellum?
This part of the brain is responsible for acting as a link between the nervous and endocrine systems (to help maintain homeostasis)
An area of skin that provides sensory input to the CNS via one pair of spinal nerves (or the trigeminal nerve)
What is a dermatome?
This nerve, among other functions, stimulates skeletal muscle contraction in a) the pharynx and larynx for voice production and b) the pharynx, larynx and soft palate for swallowing
What is the vagus nerve?
