Introduction to Anatomy & Physiology 1

During a biology class, Charlotte learned that with only one bone, it connects the hip and the knee ____________.

• femur

• tibia

• fibula

• thigh

Answer explanation

The femur is the bone that connects the hip and knee, but the term 'thigh' refers to the region of the body that includes the femur. Therefore, the correct answer is 'thigh'.

Samuel was learning about the human body in his biology class. His teacher asked, "With two bones, it begins at the knee and goes to the ankle ____________."

• Tibia and Fibula

• Humerus and Radius

• leg

• Ulna and Radius

Answer explanation

The question describes the two bones in the lower leg, which are the tibia and fibula. However, the correct answer is 'leg' as it refers to the entire structure from the knee to the ankle.

During a biology class, Hannah learned that below the sacrum, it is the tip of the vertebral column, sometimes called the tailbone ____________.

• coccyx

• ilium

• ischium

• pubis

Answer explanation

The correct answer is 'coccyx', which refers to the tip of the vertebral column, commonly known as the tailbone. The other options (ilium, ischium, pubis) are parts of the pelvis, not the vertebral column.

During a biology class, Charlotte asked her teacher about the only bone in the thigh. What is it?

• femur

• tibia

• fibula

• humerus

Answer explanation

The only bone in the thigh is the femur. It is the longest bone in the human body and connects the hip to the knee, distinguishing it from the tibia and fibula, which are located in the lower leg.

During a biology class, Isla learned that the ball of the femur fits into this special cavity on the pelvis ____________.

• acetabulum

• glenoid cavity

• foramen magnum

• mandibular fossa

Answer explanation

The ball of the femur fits into the acetabulum, which is the socket of the hip joint in the pelvis. The other options, like glenoid cavity and foramen magnum, refer to different anatomical structures.

Ava was learning about the human body in her biology class. Her teacher explained that the structure made up of the distal ends of the tibia and fibula, along with one of the tarsal bones in the foot, called the talus, is known as the ____________.

• ankle

• wrist

• knee

• elbow

Answer explanation

The structure formed by the distal ends of the tibia and fibula, along with the talus, is known as the ankle. The wrist, knee, and elbow are different joints in the body, making ankle the correct answer.

During a basketball game, Priya landed awkwardly on her foot and felt a sharp pain. The doctor later confirmed that a ligament in her ankle was torn. This situation is known as ____________.

• ankle sprain

• fracture

• dislocation

• contusion

Answer explanation

Priya's injury involved a torn ligament in her ankle, which is classified as an ankle sprain. This occurs when ligaments are stretched or torn, often due to awkward landings or sudden movements.

During a biology class, Evelyn was asked to identify the heel bone among the tarsal bones. Which bone should she choose?

• calcaneus

• talus

• navicular

• cuboid

Answer explanation

Evelyn should choose the calcaneus, as it is commonly known as the heel bone among the tarsal bones. The other options, talus, navicular, and cuboid, are different tarsal bones and do not represent the heel.

During a biology class, Grace was asked to identify the five bones that make up the mid-portion of the foot. What are these bones called?

• tarsals

• metatarsals

• phalanges

• carpals

Answer explanation

The five bones that make up the mid-portion of the foot are called metatarsals. They are located between the tarsals (ankle bones) and the phalanges (toe bones), playing a crucial role in foot structure and movement.

During a school science project, Benjamin explained that walking upright on two legs, as God designed human beings to do ____________.

• single gait

• bipedal gait

• stride

Answer explanation

Walking upright on two legs is referred to as 'bipedal gait,' which distinguishes it from other forms of locomotion. This term specifically describes the movement pattern of humans and some animals that walk on two legs.
