Seeley's Anatomy and Physiology
Chapter 9 2025/2026 Exam Questions
and Correct Answers | New Update
Functions of muscle - 🧠ANSWER ✔✔Movement of the body, maintenance of
posture, production of body heat, communication, constriction of organs and
vessels, contraction of the heart
Major properties of muscle - 🧠ANSWER ✔✔Contractility, excitability,
extensibility, and elasticity
Contractility - 🧠ANSWER ✔✔The ability of muscle to shorten forcefully
Excitability - 🧠ANSWER ✔✔The capacity of muscle to respond to a stimulus
Extensibility - 🧠ANSWER ✔✔The ability of a muscle to be stretched beyond its
normal resting length and still be able to contract
Elasticity - 🧠ANSWER ✔✔The ability of a muscle to recoil to its original resting
length after it has been stretched

, Skeletal muscle - 🧠ANSWER ✔✔Responsible for locomotion, facial expression,
posture, respiratory functions, and many other body movements, voluntarily
Smooth muscle - 🧠ANSWER ✔✔The most widely distributed type of muscle in
the body, involuntary
Cardiac muscle - 🧠ANSWER ✔✔A muscle type found only in the heart,
involuntary
Motor neurons - 🧠ANSWER ✔✔Specialized nerve cells that stimulate muscles to
contract
Z disk - 🧠ANSWER ✔✔A filamentous network of protein forming a dislike
structure for the attachment of actin myofilaments
Sliding filament model - 🧠ANSWER ✔✔The process where actin and myosin
myofilaments do not change length during contraction of skeletal muscle but,
instead, slide past one another, causing the sarcomeres to shorten
Resting membrane potential - 🧠ANSWER ✔✔The charge difference across the
plasma membrane of an unstimulated cell
Ligand - 🧠ANSWER ✔✔A molecule that binds to a receptor
