Communication
Anatomy of the CNS/PNS COLA
| Term | Definition |
|---|---|
| Effective communication system starts with: | A stimulus that triggers a response |
| Sensory Receptors | are specialized cells, usually neurons, that detect and respond to physical and chemical stimuli. |
| CNS consists of | Brain and Spinal cord |
| PNS consists of | Sensory nerves and Motor nerves |
| Sensory nerves also referred to as: | Afferent (going INTO the CNS) |
| Motor nerves also referred to as: | Efferent (coming OUT of the CNS) |
| Spinal Cord | Extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column |
| Cerebrum | Left and Right hemispheres of the brain |
| Diencephalon | includes: Thalmus and Hypothalmus |
| Brainstem | includes: Midbrain, Pons and Medulla Oblongata |
| Cerebellum | the part of the brain at the back of the skull in vertebrates, which coordinates and regulates muscular activity. |
| Within the Forebrain | Telencephalon: cerebral hemispheres Diencephalon |
| Within the Midbrain | Mesencephalon Connects Forebrain & Hindbrain |
| Within the Hindbrain | Brainstem (Pons & Medulla Oblongata) & the Cerebellum |
