Muscle Contraction and Movement

Play an AI-generated podcast conversation about this lesson

Match the following types of muscles with their control mechanism:

Voluntary muscles = Perform voluntary contractions and relaxations Involuntary muscles = Perform involuntary contractions

Match the following actions with the appropriate muscle movement:

Bending the elbow = Brain instructs the triceps muscle to contract Straightening the arm = Brain signals the triceps muscle to relax

Match the following characteristics with the types of muscles:

Voluntary muscles = Work in coordinated groups with other muscles Involuntary muscles = Controlled by autonomic nervous system

Match the following with their locations in the body:

Head and neck muscles = Responsible for facial expressions, head movements, speech, and swallowing Trunk muscles = Mainly responsible for breathing and supporting the spine Pelvic muscles = Hold organs inside the pelvic cavity firmly in place Muscles of the limbs = Include upper limb muscles with tendons connecting to wrist and fingers Signup and view all the answers

Match the following with their functions:

Thoracic muscles = Mainly responsible for breathing Muscles of the back = Hold the spinal column erect Abdominal muscles = Assist in breathing movements and balance spine muscles Lower limb muscles = Among the most powerful in the body Signup and view all the answers

Match the following with their role in posture:

Muscles of the back = Hold the spinal column erect Abdominal muscles = Keep viscera firmly in place and assist in breathing movements Upper limb muscles = Bulk at shoulder and below elbow with tendons connecting to wrist and fingers Pelvic muscles = Hold organs inside the pelvic cavity firmly in place Signup and view all the answers

Match the following with their anchorage points:

Abdominal muscles = Have strong anchorage points Pelvic muscles = Have strong anchorage points especially at the pelvis Upper limb muscles = Long tendons connect to wrist and fingers for anchorage Lower limb muscles = Have strong anchorage points especially at the pelvis Signup and view all the answers

Match the following with their specific functions:

Head and neck muscles = Responsible for facial expressions, head movements, speech, and swallowing Thoracic muscles = Attached to two or more bones and mainly responsible for breathing Muscles of the limbs = Include upper limb muscles at shoulder and lower limb muscles as most powerful Trunk muscles = Support breathing, spine, viscera, and organs inside pelvic cavity Signup and view all the answers
