CSD 412
Exam 1 (Ch.1, Ch.11-cerebrospinal fluid)
| Term | Definition |
|---|---|
| Anatomy | Study of the structure of an organism |
| Physiology | Study of the function of a living organism and its components |
| Neurology | Study of the diseases of the nervous system |
| Motor Neurons | Send information to muscles |
| Betz Cells | Provide the initial response from the conscious brain |
| Frontal Plane | Divides body into front & back halves |
| Midsagittal Plane | Exactly the same on both sides, right down the middle |
| Sagittal Plane/Sideview | Divides the body or body part into right & left halves |
| Transverse Plane | |
| Coronal Plane | |
| Anterior | Front |
| Ventral | Pertaining to the belly or anterior surface |
| Posterior | Toward the rear |
| Dorsal | Pertaining to the back of the body |
| Superficial Surface | On or near the surface |
| Peripheral Surface | Relative to the periphery or away from (ex.: if able to peel back first 5 layers of skin) |
| Deep | Further from the surface; peel back all layers |
| Distal | Away from the midline (ex.: fingers are distal to head) |
| Proximal | Next to (ex.: shoulder is proximal to head) |
| Superior | Above looking down (adults are superior to kids) |
| Inferior | Down looking up (kids are inferior to adults (shorter)) |
| Prone | Face down on the floor (ex.: babies are prone during tummy time) |
| Supine | Laying on the back |
| Lateral | Outside looking in on the sides |
| Medial | Inside looking out on the sides |
| Rostral | Towards the head |
| Cranial | Towards the skull |
| Caudal | Towards the ground/tail |
| Gray Matter | Refers to cell bodies (where nuclei is stored, power house of the cell, mitochondria) |
| White Matter | Refers to myelinated fibers (most motor neurons are myelinated) |
| Glial Cells | Supportive cells |
| Action Potential | Electrical activity of a neuron that conveys information |
| Dendrite | Receives; Input location on neuron for information (gather info from other cells) |
| Axon | Transmits; Output location on neuron for information |
| Soma | Body of neuron (where the nucleus is) |
| Nucleus | Contains DNA the synthesises proteins & enzymes |
| Golgi Apparatus | Collecting, packaging, & releasing proteins & liquids fabricated within the systems |
| Enzymes | Break down & recycle other organels |
| Mitochondria | Energy generators for the cell; power house of the cell |
