What are the three types of muscle tissue?
Smooth, Skeletal, Cardiac.
What are the characteristics of skeletal muscles?
Skeletal muscles are striated, voluntary, and attached to bones.
Define 'Origin' in muscle anatomy.
The origin is the fixed attachment point of a muscle.
Define 'Insertion' in muscle anatomy.
The insertion is the movable attachment point of a muscle.
What is the difference between the origin and insertion points?
The origin is stationary while the insertion moves towards the origin during contraction.
What is an Agonist muscle?
The agonist is the primary muscle responsible for movement.
What are Synergists in muscle function?
Synergists are muscles that assist the agonist in performing a movement.
What are Antagonists in muscle function?
Antagonists are muscles that oppose the action of the agonist.
What is a Fixator muscle?
A fixator stabilizes the origin of the agonist muscle.
Identify the agonist, synergists, antagonists, and fixator in a bicep curl.
Agonist: Biceps brachii; Synergists: Brachialis, Brachioradialis; Antagonist: Triceps brachii; Fixator: Muscles of the shoulder.
What are the two types of muscle contractions?
Isotonic and Isometric.
What is an Isotonic contraction?
An isotonic contraction involves muscle shortening and movement, such as lifting a weight.
What is an Isometric contraction?
An isometric contraction involves muscle tension without movement, such as holding a weight steady.
What is a sarcomere?
A sarcomere is the basic contractile unit of a muscle fiber.
What is the largest muscle in the human body?
The gluteus maximus.
What is the longest muscle in the human body?
The sartorius.
What is the smallest muscle in the human body?
The stapedius.
How many skeletal muscles are in the human body?
About 600 skeletal muscles.
How many muscles are needed to smile?
Approximately 17 muscles.
How many muscles are needed to frown?
Approximately 43 muscles.
What percentage of body weight do skeletal muscles make up?
Skeletal muscles make up about 40% of body weight.
What percentage of body heat comes from muscle contractions?
About 85% of body heat comes from muscle contractions.
Which muscles make up the hamstrings?
Biceps femoris, Semitendinosus, Semimembranosus.
Which muscles make up the quadriceps?
Rectus femoris, Vastus lateralis, Vastus medialis, Vastus intermedius.
Which muscles make up the groin?
Adductor longus, Adductor brevis, Adductor magnus.
