Struct & An. Brain
| Term | Definition |
|---|---|
| Meninges | A three layer protective covering of the brain |
| Medial Longitudinal Fissure | Separating the two Cerebral hemispheres |
| Gyri | Ridges of the brain |
| Sulci | Shallow grooves |
| Cerebral Cortex | Grey Matter (outer 2-4 mm of brain) the most highly evolved area of the brain |
| Frontal Lobe | Intellectual functions: reasoning and abstract thinking, aggression, sexual behavior, olfaction, speech, and voluntary movement (precentral gyrus) |
| Parietal Lobe | Body sensory awareness, taste, (postcentral gyrus), language, abstract reasoning, and body imaging |
| Temporal Lobe | Formation of emotions (love, anger, aggression, compulsion, sexual behavior), interpretation of language and sound, major memory center |
| Occipital Lobe | Receives, interprets, and discriminates visual stimuli from optic tract |
| Cerebellum | Posterior to cerebrum and attached to brain stem, controlling equilibrium and motor coordination and muscle tone |
| Brain Stem | Diencephalon (Forebrain), Midbrain, Hindbrain |
| Diencephalon (Forebrain) | Thalamus, Hypothalamus, Epithalamus and Hypophysis |
| Thalamus | Relay station, all sensory input must travel through here (except smell) before it reaches the cerebral cortex |
| Hypothalamus | Involuntary body functions (tasting, smelling, resting, blood sugar levels, homeostasis), pituitary gland is located here |
| Midbrain | Cerebral Aqueduct, Cerebral Peduncle |
| Cerebral Aqueduct | Connects 3rd and 4th ventricles to supply cerebrospinal fluid form choroid plexus |
| Cerebral Peduncle | Long descending tracts from the cerebral cortex to the pons and medulla |
| Hindbrain | Pons, Medulla Oblongata |
| Pons | Bridge between the fourth ventricle and cerebellum |
| Medulla Oblongata | Attached to spinal cord, controls breathing, blood pressure, swallowing, and heart rate |
| Olfactory Bulbs | Responsible for smell |
| Optic Chiasma & Optic Nerves | Responsible for sight |
| Pituitary Gland | The main endocrine gland, responsible for growth and production of milk in females |
| # of Cranial Nerves (all mammals possess) | 12 |
| Nervous tissue is made up of 2 types of cells: | Supporting cells and neurons |
| Supporting Cells | Neuroglia (many types of nerve cells that support, insulate and protect neurons), Astrocytes (form living barrier between capillaries & neurons), Microglia, Ependymal cells, Oligodendrocytes, Schwann cells, and Satellite cells |
| Neurons (Nerve cells) | Specialized to transmit messages (nerve impulses) from one part of the body to another. Although different neurons have different structures, they all have common features |
| Cell body | Contains the nucleus and is the metabolic center of the cell |
| Processes or fibers | Extend from the cell body |
| Dendrites | Neuron processes that conduct electrical currents toward the cell body |
| Axons | Neuron processes that conduct electrical currents away from the cell body |
