| What are 3 characteristics of connective tissue proper? | Few cells; Lots of matrix; Fibers inbetween cells | ||||
| What are the 3 types of fibers in connective tissue proper? | Elastic; Reticular; Collagen | ||||
| What is the main function of connective tissue proper? | It is mechanically involved in tying pieces together, connecting them, and holding them together. | ||||
| What is ground substance? | The matrix of connective tissue that is mostly made of glycoproteins. | ||||
| What is a fibroblast? | The most common connective tissue cell. It produces fibers and the matrix. | ||||
| What are macrophages? | Cells that find and eat infection and other debris. | ||||
| What are mast cells? | White blood cells in connective tissue that play a role in the immune system response of the body. | ||||
| What are plasma cells? | Cells that produce antibodies in the connective tissue proper. | ||||
| What is dense connective tissue? | Tissue that has many fibers. It is made for areas that take a lot of stress. | ||||
| What is loose connective tissue? | Tissue that does NOT have many fibers. It is made for areas that DO NOT take a lot of stress. | ||||
| What is regular connective tissue? | Tissue that has fibers all going in one direction. | ||||
| What is irregular connective tissue? | Tissue that has fibers going in many different directions. | ||||
| Describe loose, irregular connective tissue. | Fibers go in all directions; Found under the skin; AKA 'areolar tissue' | ||||
| What is adipose tissue? | Nucleus always squashed to one side; Made of fibroblasts and lipid (fat) molecules; Where the body stores excess nutrients | ||||
| What are the two basic types of bone tissue? | Dense or compact bone and cancellous or spongy bone | ||||
| What are trabeculae? | A network of interconnected plates in the cancellous bone that serve as a supporting lattice. | ||||
| What are lamellae? | Concentric rings of bone that are in haversian systems and made by osteocytes. | ||||
| Define osteocytes. | Bone cells | ||||
| What are erythrocytes? | Red blood cells | ||||
| What are the 4 elements found in blood? | Erythrocytes (red blood cells); Leukocytes (white blood cells); Thrombocytes (platelets); Plasma | ||||
| What is a platelet? | A packet of chemicals surrounded by a cell membrane that has been pinched off of a megakaryocyte. | ||||
| What is a megakaryocyte? | A very large cell located in bone marrow that is responsible for creating thrombocytes. | ||||
| What are the two types of cells in nervous tissue? | Neurons and neuroglia | ||||
| Structurally, what are the 3 basic parts of a neuron? | Cell body or perikaryon; Processes (2 types); Myelin sheath | ||||
| What are the two possible process of a neuron? | Axons and dendrites | ||||
| What is the function of an axon? | It carries nerve impulses away from the neuron's cell body. | ||||
| what is the function of a dendrite? | It carries nerve impulses to the neuron's cell body. | ||||
| What is the myelin sheath? | A layer of lipid material that surrounds a nueron's process and is produced by neuroglia cells. |
