ANATOMY AND PHYSIOLOGY TEST 1- What is the main function of the muscular system: Contraction 2- Cardiac muscle cells are: *involuntary voluntary 3- Cardiac muscle name: myocardium 4- What are the muscles involved in respiration: diaphragm and intercoastal 5- what covers muscle fiber: endomysium 6- what covers fascicle: perimysium 7- what covers the entire muscle: epimysium 8- what is the contractile unit of a muscle: sarcomere 9- what structure goes from bone to bone: Ligaments 10- What structure attaches muscle to bone: Tendon 11- Example of a tendon: Achilles tendon 12- Plasma membrane od a muscle fiber: Sarcolemma 12- Cytoplasm of a muscle fiber: Sarcoplasm 13- Stem Cells: Myoblast 14- Sheet like connective tissue: Aponeurosis 15- Rod like connective tissue: Tendon 16- What connective tissue touches a bone: Epimysium **** 17- Red pigment, provides oxygen needed for muscle activity: Myoglobin 18- Pre synaptic structure: Axon Terminal 19- Little space: Synaptic clef 20- Post synaptic structure: lands in a singles muscle cell 21- Which ones are the light bands: I bands 22- Bisects I band: Z disc 23- Example of a neurotransmitter: Acetylcholine 24- Thick sheet of connective tissue that separates groups of muscle: Fascia 25- Example of a fusiform muscle: Biceps brachii 26- Example of a Parallel muscle: Rectus femoris, zygomaticus major of the face 27- Examples of a Triangular/covergent muscle: pectoralis major, temporalis 28- Examples of a circular muscle: orbicularis oris, orbicularis oculi 29- Examples of unipennate: Palmar interosseous 30- Examples of bipennate: rectus femoris 31- Examples of multipennate: deltoid 32- What is the point where nerve fiber meets any target cell: synapse 33-Protein found in the thin filaments: Actin 34- Where do you find the H zone: Middle of the dark band 35- What divides the H zone: M line 36- Protein found in the elastic filaments: Titin 37- Protein found in the thick filaments: Myosin 38- What structure disappears when the muscle contracts: H zone 39- What type of muscle is multinucleated: Skeletal 40- What type of muscle has 1-2 nucleus: Cardiac 41- Which one is the protein that does the slide: Actin 42- Peristalsis: (wave) that allows food to go through 43- Varicosity: unique on smooth muscle 44- Neuron side of neuromuscular junctions: Axon Terminal 45- End line of sarcomere: Z disc 46- Action potential: gives a total impact to the muscle to allow contraction
