Muscular System Flashcards
Adductors
It is an important group of muscles located on your inner thighs that serve to bring your legs toward the center of your body.
Biceps brachii
They are large, thick muscles on the ventral portion of the upper arm.
Biceps femoris
They are long muscles in the posterior compartment of the thigh that is responsible for movement at both the hip and knee joints.
Buccinators
They are muscles that play an active role along with the orbicularis oris and superior constrictor muscle during swallowing, mastication, blowing, and sucking.
Deltoid
They are muscles in your shoulder, which is the ball-and-socket joint that connects your arm to the trunk of your body.
Extensors
They are muscles whose contraction extends or straightens a limb or other part of the body.
External intercostals
They are small muscles located in between each rib, starting at the first rib and extending down to the 11th rib.
External oblique
It is a muscle situated on the lateral and anterior parts of the abdomen.
Fibularis longus
It is a superficial muscle in the lateral compartment of the leg.
Flexors
It is a muscle that flexes a joint.
Frontalis
It is a muscle responsible for elevating the eyebrows.
Gastrocnemius
It is the chief muscle of the calf of the leg, which flexes the knee and foot. It runs to the Achilles tendon from two heads attached to the femur.
Gluteus maximus
It is any of three muscles in each buttock that move the thigh, the largest of which is the gluteus maximus.
Gluteus medius
It is a muscle lying between the gluteus maximus and gluteus minimus.
Internal oblique
It is a muscle found on the lateral side of the abdomen.
Latissimus dorsi
It is a broad, flat muscle that occupies the majority of the lower posterior thorax.
Masseter
It is a muscle that runs through the rear part of the cheek from the temporal bone to the lower jaw on each side and closes the jaw in chewing.
Orbicularis oculi
It is a muscle located in the eyelids.
Orbicularis oris
It is a multi-layered muscle that attaches through a thin, superficial musculoaponeurotic system to the dermis of the upper lip and lower lip and serves as an attachment site for many other facial muscles around the oral region.
Pectoralis major
It is the superior most and largest muscle of the anterior chest wall.
Rectus abdominus
They are the muscles that make up the top layer of your abdominal muscles, commonly referred to as your “six-pack.”
Rectus femoris
It is a muscle that flexes the hip along with the sartorius and iliopsoas and extends the lower leg at the knee, working in conjunction with the other three quadriceps muscles.
Sartorius
It is the longest muscle in the body, spanning both the hip and the knee joints.
Semimembranosus
It is the most medial of the three hamstring muscles in the thigh.
