Muscles in Action
The most important muscle responsible for breathing.
What is the diaphragm
These muscles make up the quadriceps femoris.
What are Rectus femoris, vastus lateralis, vastus imtermedius and vastus medialis
The basic organization of sarcomere.
This muscle fascicle arrangement is seen in the orbicularis oris.
What is Circular.
This process aids in skeletal muscle relaxation after contraction.
What is acetylcholinesterease degrades acetylcholine
Prime mover of neck flexion.
Sternocleidomastoid
The hamstring muscles.
Biceps femoris, semitendinosus and semimembranosus
The structural organization of skeletal muscle (from organ to myofilament)
Muscle, fascicle, muscle fiber, myofibril, sarcomere, myofilament
Pectoralis major muscle fascicle arrangement.
What is convergent
Extensor muscles of the upper limb lie almost exclusively in this region of that limb
what is posterior
What are Iliocostalis, longissimus, spinalis
4 muscles of the rotator cuff.
Supraspinatus, infraspinatus, teres minor, subscapularis
5 types of muscle fascicle arrangement.
What are Parallel, Convergent, Circular, Pennate, Fusiform
This muscle fascicle arrangement is seen in fusiform - biceps brachii & sternocleidomastoid (strap like)
parallel
When the diaphragm contracts.
What is flatten
4 main pairs of muscles important for mastication.
Masseter, temporalis, Pterygoid and buccinator
4 main muscles that form the abdominal wall.
External oblique, Rectus abdominis internal oblique, Transversus abdominis
This muscle type, is red, hydrolyze ATP at a slow rate, slow contraction, very resistant to fatigue and high capacity to generate ATP by oxidative metabolic processes.
What is slow oxidative fibers
Muscle fascicle arrangement that follows: insert into one side of the tendon (extensor digitorum longus), insert into the tendon from both sides (rectus femoris), fascicles insert into one large tendon from all sides (deltoid).
what is pennate
An important function of the soleus muscle.
What is plantar flex the foot
The prime mover of thigh flexion.
Illiopsoas (made up of Psoas major and illiacus)
2 muscles that form the pelvic floor.
Levator ani (Pubococcygeus, Iliococcygeus), Coccygeus
This muscle fiber type contain large amounts of myoglobin, many mitochondria and blood vessels. They are red, hydrolyze ATP at a slow rate, have a slow contraction velocity, very resistant to fatigue and have a high capacity to generate ATP by oxidative metabolic processes.
Fast oxidative fibers
The deepest muscle of the anterior abdominal wall.
transverse abdominis
A deltoid injection is given here.
What is 5 cm below the greater tubercle of the humerus.
