Lesson Worksheet: Muscles and Movements Science
In this worksheet, we will learn practice stating examples of types and groups of muscles, measuring muscle strength, and describing how antagonistic pairs work together in the human body.
Q1:
Which statement about muscles is true?
- AThe force exerted by your muscles is measured in kilograms.
- BMuscles work in pairs by contracting at the same time.
- CMuscles can push and pull and work together at a joint.
- DAbdominal muscles can help with breathing during heavy exercise.
- ELigaments attach muscles to bones to allow movement.
Q2:
What is the difference between a ligament and a tendon?
- ATendons can contract but ligaments cannot.
- BTendons attach muscle to bone but ligaments attach bone to bone.
- CTendons are more flexible and elastic than ligaments.
- DTendons are found at joints and ligaments are not.
- ETendons work in antagonistic pairs but ligaments do not.
Q3:
Complete the sentence: When a muscle , it gets shorter and so pulls on the bone it is attached to. When a muscle , it returns to its orginal size.
- Arests, tightens
- Bcontracts, relaxes
- Cconstricts, expands
- Drelaxes, contracts
Q4:
What is the name of the muscle that makes up your heart?
- ACardiac muscle
- BTriceps muscle
- CGut muscle
- DBiceps muscle
Q5:
The figure shows antagonistic muscles bending and straightening the arm.
What is the name of structure X?
- ATendon
- BMuscle
- CLigament
- DBone
Which label (A, B, C, or D) is pointing to the triceps relaxing?
- AB
- BD
- CA
- DC
Q6:
The figure shows a student measuring his muscle strength by pushing down on a scale as hard as he can.
What muscle group is he measuring?
- AGluteals
- BShoulder
- CTriceps
- DAbdominals
Q7:
The figure shows an arm holding a weight of 25 N, positioned 0.25 m from the pivot at the elbow. The biceps muscle is attached to the bone by a tendon that is 0.05 m from the elbow pivot.
Calculate the force, in newtons, applied by the biceps muscle to hold the weight in position.
Q8:
The figure shows some of the major muscle groups in the human body.
Which group (A, B, C, D, or E) is the abdominal muscles?
- AGroup D
- BGroup B
- CGroup C
- DGroup A
- EGroup E
Q9:
The figure shows some of the major muscle groups in the human body.
Which muscle group (A, B, C, or D) pulls the heel up?
- AGroup B
- BGroup A
- CGroup D
- DGroup C
