General Functions of Muscle
What two factors contribute to body heat production?
1. Catabolism of glucose 2. Muscle contraction
In regards to movement and propulsion, skeletal muscle is responsible for what?
1. Locomotion (walking, running) 2. Other body movements (grasping with hands, breathing movements, turning head, eye movements)
On average, skeletal muscle makes up about ...% of body mass
40%
In regards to movement and propulsion, what are smooth muscles' four functions?
Propulsion of nutrients through digestive tract, Transport of urine from kidneys to bladder (peristalsis), Micturition (urination), Parturition (child birth)
What type of muscle is responsible for body heat production?
Skeletal
What type of muscle directly regulates blood pressure? How?
Smooth muscle through contractions in arteriole walls
What type of muscle moves blood through the cardiovascular system?
cardiac
What are the four general functions of muscles?
movement/propulsion, regulation of blood pressure, posture (skeletal), body heat production
What is posture maintained by?
muscle tonus (Slight continual muscle contractions that maintain tension in body regions to maintain postural orientation)
