| Question | Answer |
|---|---|
| What are the 3 embryonic regions of the brain? | Prosencephalon/forebrain, Mesencephalon/midbrain, and rhombencephalon/hindbrain |
| What are the 3 layers on the meninges? | Dura mater, arachnoid mater, and subarachnoid space then the Pia mater |
| What are the 2 ventricles that occupy the center of each cerebral hemisphere known as? | Lateral Ventricles |
| Where is Cerebrospinal fluid received from? | Blood Capillaries called CHOROID PLEXUSES |
| Fluid from the lateral ventricles flow through the ____ to then inter the 3rd ventricles | Interventricular Foramina |
| The third ventricle drains into the 4th ventricle by way of the_____ | Mesencephalic (cerebral) aqueduct |
| When fluid accumulates in the lateral and third ventricles, it produces a condition called? | Hydrocephaly |
| Ridges of the convolutions are called? | Gyri or Gyrus |
| The depressions of the convolutions are called? | Suli/sulcus or fissures |
| What's the difference between the Sulcus and the Fissures? | Fissures are deeper |
| What does the lateral fissure (sulcus) separate? | The Temporal lobe from the frontal and parietal lobes |
| What is the Frontal lobe responsible for? | intellect, abstract, reasoning, creativity, social awareness, and language. |
| What area is responsible for controlling the formation of speech? | Broca Area or the Motor Speech area |
| Where is the Central sulcus found? | the posterior border of the frontal lobe |
| What's responsible for motor control? | Precentral Gyrus or the Primary Motor Cortex |
| What is the Parietal Lobe responsible for? | Sensory Reception (Pain, Heat, Cold, ect) |
| What is responsible for the formation of Language, such as the recognition of written and spoken languages and in forming sentences? | Wernicke Area |
| What is the Occipital Lobe responsible for? | Primary Visual Area, shape color and distance of an object |
| What does the Transverse fissure separate? | Occipital lobe and the cerebellum |
| What is the Temporal Lobe responsible for? | the nature of sound (music, noise, speech) and the location, distance, pitch, and rhythm |
| What does the Temporal Lobe contain? | Primary Auditory Cortex (interprets hearing) Olfactory Centers (sense of smell) Gustatory Centers (sense of taste) |
| What is the Left Cerebral Hemisphere involved in? | Language and reasoning |
| What is the Right Cerebral Hemisphere involved in? | Space and pattern perceptions, artistic awareness, imagination, and music comprehension |
| The Cerebellum has much finer folds of neural tissue called? | Folia |
| What is the Medulla Oblongota responsible for? | Respiratory rate control, control of blood pressure, and other vital centers |
| What does the Corpus Callosum look like and do? | A C-Shape which connect the two cerebral hemisphere |
| Where is the Thalamus and what does it do? | It's the lateral wall around the third ventricle and is a relay center that recieves almost all the sensory information from the body and projects it to the cerebral cortex |
| Where is the Hypothalamus and what does it do? | Located below the thalamus and it direct the ANS and is involved with the pituitary gland functions. It's the Center for thirst, water balance, pleasure, rage, sexual desire, hunger, sleep patterns, temperature, and aggression |
| What does the Pineal gland do? | its an endocrine gland that secretes melatonin, a hormone that regulates daily rhythms, such as waking up and sleeping |
| What is the Corpora quadrigemina consist of and what does it do? | It's composed of the Superior colliculi(areas of visual reflexes) and inferior colliculi(areas of auditory reflexes) |
| The hindbrain consists of an anterior bulge known as_____ | Pons |
| What does the Pons do? | Carries sensory information from the inferior regions of the body to the thalamus |
| What does the Cerebellum do? | muscle coordination, maintenance of posture, the conceptualization of the passage of time and other cognitive functions |
| Arbor Vitae is also known as_______ | Tree of life |
| The Folia is also known as _____ | Leaves |
| Olfactory Nerve | Sensory from nose |
| Optic Nerve | Sensory info from eye |
| Oculomotor nerve | From the eye muscles |
| Trochlear nerve | From the eye muscles |
| Trigeminal Nerve | Face |
| Abducens Nerve | Eye Muscles |
| Facial Nerve | Facial expressions |
