Question | Answer |
connects spinal cord to brain; integration of reflexes necessary for survival | Brainstem |
involved in control of locomotion, balance, posture, learning new movements | Cerebellum |
involved with higher order functions | Diencephalon |
4 parts of the diencephalon | thalamus, subthalamus, epithalamus, hypothalamus |
The telencephalon of a late embryo becomes the ____________ in an adult | Cerebrum |
The metencephalon of a late embryo becomes the ____________ and _________ in an adult | Cerebellum and Pons |
The myelencephalon of alate embryo beomes the ___________ in an adult | Medulla oblongata |
Regulates: heart rate, blood vessel diameter, respiration, swallowing, vomiting, hiccupping, coughing, and sneezing (Survival Functions) | Medulla oblongata |
Structure where descending nerve tracts on the anterior surface of the medulla oblongata decussate (cross) | Pyramids |
Nuclei within the medulla oblongata that help regulate balance, coordination, modulation of sound from inner ear | Olives |
Sleep and Respiratory Center | Pons |
Where are Pontine Nuclei found? | Pons |
involved in visual reflexes | superior colliculi |
involved in hearing reflexes | inferior colliculi |
associated with ordered volitional movement | Substantia Nigra |
Associated with superior colliculi, inferior colliculi, substantia nigra, and red nuclei | Midbrain (Mesencephalon) |
Group of nuclei scattered throughout brainstemthat controls cyclic activities such as the sleep-wake cycle | Recticular Formation |
Coordination and motor control | Cerebellum |
fiber tracts in the cerebellum that communicate with other parts of brain | Cerebellar peduncles |
Largest cells in the CNS that recieve 200,000 synapses and are inhibitory | Purkinje cells |
List the major cerebellar functions: | Balance, eye movements, posture, locomotion, fine motor coordination, and learning complex movements |
The "relay center" involved with motor functions, mood modification, emotion regulation, emotion regulation, and sensory integration | Thalamus |
Where is the Pineal Gland located? | Epithalamus |
Helps regulate the biological clock and influences sleepiness | Pineal Gland |
Part of the Epithalamus that produces emotional and visceral responces to odors | Habenular Nucleus |
List some of the general functions associated with the Hypothalamus | Autonomic, endocrine, muscle control, temperature regulation, metabolism, emotions, sleep-wake cycle, sexual development. |
between the precentral gyrus (primary motor cortex) and postcentral gyrus (primary somatic sensory cortex) | Central sulcus |
voluntary motor function, motivation, aggression, sense of smell, mood | Frontal Lobe |
reception and evaluation of sensory information except smell, hearing, and vision | Parietal Lobe |
reception and integration of visual input | Occipital Lobe |
reception and evaluation for smell and hearing; memory, abstract thought, judgment. Insula is within | Temporal Lobe |
Nuclei associated with motor function control and Parkinson's Disease | Basal Nuclei |
where is CSF produced | Choroid Plexus |
True or False: The brain requires insulin | False |
Cranial nerve associated with special sense of smell | Olfactory |
Cranial nerve associated with special sense of vision | Optic |
Cranial nerve associated with the sphincter of the pupil and ciliary muscle of the lens | Oculomotor |
Two cranial nerves associated with external eye muscles | Trochlear and Abducent |
List the three branches of the Trigeminal Nerve | Opthalmic, maxillary, and mandibular |
Cranial nerve associated with sensory, motor, sympathetic and parasympathetic functions | Trigeminal |
Cranial nerve associated with special sense of taste, facial expressions, salivary glands, lacrimal glands and nasal cavity | Facial |
Cranial nerve associated with special senses of hearing and balance | Vestibulocochlear |
Cranial nerve associated with taste, pharynx, tonsils, swallowing, and salivary glands. | Glossopharyngeal |
The "wandering nerve" with sensory, motor, and parasympathetic functions | Vagus |
Cranial nerve associated with the muscles of the neck | Accessory |
Cranial nerve associated with tongue muscles | Hypoglossal |
