ANP 1105 Midterm #1 (uottawa)Test
Exam Questions and All Correct
Answers 2025-2026 Set.
Epimysium - Answer outermost layer, most robust, connects muscles to bones
Perimysium - Answer Connective tissue surrounding a fascicle
Endomysium - Answer Connective tissue surrounding a muscle fiber
Deep fascia - Answer dense connective tissue on the surface of individual muscles
wraps bundles of muscles together and are more robust than Epimysium
characteristics of muscles - Answer excitability, contractility, extensibility, elasticity
Functions of muscles - Answer Produce movement:
Maintain posture and body position
Stabilize joints
Shoulder joints is stabilized by rotator cuff muscles
Generate heat - shivering
fasicles - Answer bundles of muscle fibers that help determine their shape
Excitability - Answer ability to respond to stimuli
Contractility - Answer ability to shorten forcibly when stimulated
Extensibility - Answer ability to be stretched
Elasticity - Answer The ability of a material to bounce back after being disturbed
, Sacroplasm - Answer cytoplasm of a muscle cell
Glycogen - Answer Stores glucose
Myogoblin - Answer stores oxygen
Myofibrils - Answer myofilaments (actin, myosin, etc.) arranged in a pattern, forming end-to-
end sarcomeres
Myofilaments - Answer protein strands
Striations - Answer alternate dark and light bands found on skeletal and cardiac muscle
A-Bands - Answer dark regions
H zone - Answer lighter region in middle of dark A band
M line - Answer line of protein (myomesin) that bisects H zone vertically
l bands - Answer A light band on each side of the Z line of striated muscle fibers
Z disc - Answer coin-shaped sheet of proteins that anchors the thin filaments and connects
myofibrils to one another
Sarcomeres - Answer area between two Z discs
Smallest contractile unit
gives this muscle type the name striated muscle
Actin - Answer thin filaments
Extend across I band and partway in A band
Anchored to Z discs
