CHAPTER 11 PART 1

What is the origin of a muscle/tendon?

• The more flexible end of a muscle attached to a bone

• The less mobile end of a muscle/tendon attached to a bone

• The middle part of a muscle

• The end of a muscle that contracts

What is the insertion of a muscle?

• The less mobile end of a muscle/tendon attached to a bone

• The middle part of a muscle

• The more flexible end of a muscle attached to a bone, usually by tendons

• The end of a muscle that contracts

Where are the origins and insertions of axial muscles primarily located?

• On the appendicular skeleton

• On the axial skeleton

• Outside the skeletal structure

• On the surface of the skin

What is one of the functions of axial muscles?

• Regulating heart rate

• Assisting in digestion

• Facilitating facial expression

• Enhancing visual acuity

Axial muscles support and protect which of the following?

• Only the head and vertebra

• Only the pelvic organs

• Abdominal and pelvic organs

• The limbs and appendages

Where do appendicular muscles have their origin?

• On the axial skeleton

• On the girdle or proximal regions of appendicular bones

• On the distal regions of appendicular bones

• On the skull

What do appendicular muscles control?

• Movements of the head and neck

• Movements of the heart and lungs

• Movements of upper and lower limbs

• Movements of the axial skeleton

Appendicular muscles also control movements of which structures?

• Cranial and facial bones

• Pectoral and pelvic girdles

• Vertebral column

• Thoracic cage

How are appendicular muscles organized?

• Based on their size

• Based on their function

• Based on their locations

• Based on their strength

What does a tendon attach to?

• Bone, skin, or another muscle

• Only to another muscle

• Only to skin

• Only to bone
