Muscles Flashcards
types of muscle tissue
skeletal, smooth, cardiac
skeletal muscle
strained muscle/ voluntary; contracts rapidly found in fibers that connect t tendons that attach to bones
smooth muscle
no striations & involuntary; twi layers, contracts slow and sustained, found in stomach and respiratory system
cardiac muscle
strained and involuntary; slow contraction and controlled, found in heart
muscles functions
movement, maintaining posture, generating heat, stabilizing joints
muscles are responsible for mobility of body
movement
responsible for skeletal muscle
maintaining posture
maintaining normal body temperature
generating heat
true or false: muscles stabilize join that have poor fit
true
muscles properties
excitability, contractility, extensibility, elasticity
receive and respond to stimulus
excitability
can forcibly shorten themselves when stimulated
contractility
can be stretched
extensibility
can return back to normal state after being stretched
elasticity
muscles fatigue
lactic acid build up when body uses more oxygen in tissues than normal, leading to soreness, weakness, and burning sensation
