Anatomy Muscular System

3. Consisting of spindle-shaped, nonstriated muscle cells
5. Respiration in which oxygen is consumed and glucose is broken down entirely
6. The movable attachment of a muscle as opposed to its origin
8. Muscle composed of cylindrical multinucleate cells with obvious striations
10. A process in which glucose is broken down in the absence of oxygen
13. The connective tissue enveloping bundles of muscle fibers
15. Inability of a muscle to contract even while be stimulated
16. The smallest contractile unit of muscle
18. Chemical released by neurons that bind to receptors of neurons, and stimulate them

1. Contractile organelles found in the cytoplasm of muscle cells
2. A motor neuron and all the muscle cells it supplies
4. Organ system consisting of skeletal muscles and their connective tissue attachments
7. Specialized muscle of the heart with striations
9. The thin connective tissue surrounding each muscle cell
11. The muscle attachment that is not movable or is less moveable than the intersection
12. Contractile proteins found in muscle; makes up the thick filaments
14. Sustained partial contraction of a muscle in response to stretch receptor inputs
17. Contractile proteins found in muscle; makes up the thin filaments
