THE CELL

THE CELL. Cell - from the Latin word cella meaning small room. Robert Hooke (about 1670 ) - first to use term in a biological sense. Used it to describe the small, organized compartments he observed in dead cork tissue. Not empty - contained "jellylike" material - cell cytoplasm

The Muscular System

The Muscular System. Chapter 8. Structure of a Skeletal Muscle. Layers of fibrous connective tissue called fascia separate an individual skeletal muscle from adjacent muscles and hold it in position Fascia may project beyond the end of the muscle forming a tendon. Cont.

Muscles

Muscles. Muscles work by contracting. Muscles pull. A pair is needed to move a bone two ways. An antagonistic pair. A muscle is made up of bundles of muscle cells. Muscle cells are made of bundles of myofibrils. These are groups of protein fibres.

Filaments

Filaments. Resting state. Electrical impulse (Action Potential) reaches axon terminal. Impulse opens Calcium Channels, rapid influx of Calcium into terminal. Vesicles with acetylcholine (Ach) bind to cell membrane & releases Ach into synaptic cleft.
