Welcome to the electronic human anatomy and physiology classroom of the 21st century. This class warm-up or bell ringer is related to the upper and lower extremities of the human skeleton. This activity will present several important facts and features of the skeleton system.
This warm up will present 10 questions and answers in randomized order for each unlimited number of attempts.

• 1.

### How many bones are found the pectorial and pelvic girdles, this includes both hands and feet?

• A.

28

• B.

49

• C.

126

• D.

146

C. 126
Explanation
The pectoral and pelvic girdles consist of the bones that connect the upper and lower limbs to the axial skeleton. The pectoral girdle consists of the clavicle and scapula on each side, while the pelvic girdle consists of the hip bones. Each upper limb has 30 bones (including the hand) and each lower limb has 30 bones (including the foot). Therefore, the total number of bones in both the pectoral and pelvic girdles, including both hands and feet, would be 30 + 30 + 2 + 2 = 64. Therefore, the given answer of 126 is incorrect.

### How many miles does an average person walk in a lifetime?

• A.

1 million miles

• B.

115,000 miles

• C.

4 miles

• D.

25,000 miles

B. 115,000 miles
Explanation
The correct answer is 115,000 miles. This is an estimation of the average distance that an average person walks in their lifetime. It takes into account factors such as daily activities, exercise, and general mobility. Walking is a common form of transportation and physical activity for most individuals, and over the course of a lifetime, the accumulated distance can reach 115,000 miles.

The correct answer is Brannock Device. The Brannock Device is a measuring instrument used to accurately measure the length and width of a person's foot. It is commonly used in shoe stores to determine the correct shoe size for customers. The device consists of a metal frame with movable sliders and a scale that displays the measurements. The Brannock Device is named after its inventor, Charles F. Brannock, who patented it in 1925.

### Where is the Capitate bone located?

• A.

Arm

• B.

Leg

• C.

Hand

• D.

Foot

• E.

Vertebral column

C. Hand
Explanation
The Capitate bone is located in the hand. It is one of the carpal bones and is situated in the middle of the second row of carpals, between the trapezoid and hamate bones.

### Where is the navicular bone located?

• A.

Arm

• B.

Leg

• C.

Hand

• D.

Foot

• E.

Vertebral column

D. Foot
Explanation
The navicular bone is located in the foot. It is one of the tarsal bones and is situated on the medial side of the foot, between the talus bone and the cuneiform bones. It helps to support the arch of the foot and plays a crucial role in maintaining the foot's stability and mobility during walking and running.

### When is the best time of day to try on shoes?

• A.

The earlier the better

• B.

Late in the afternoon

• C.

Right after you eat

• D.

Right before bedtime

B. Late in the afternoon
Explanation
The best time of day to try on shoes is late in the afternoon. This is because our feet tend to swell throughout the day due to walking and standing, so by late afternoon, our feet are at their largest size. Trying on shoes at this time ensures a more accurate fit, as it accounts for any swelling that may occur during the day.

### What time of day is the best for clipping your toenails?

• A.

After morning errands

• B.

After taking a shower

• C.

After you have relaxed

• D.

After you have eaten

B. After taking a shower
Explanation
Clipping your toenails after taking a shower is the best time of day because the warm water softens the nails, making them easier to trim. The moisture from the shower also helps prevent the nails from splintering or breaking. Additionally, showering before clipping your toenails ensures that your feet are clean, reducing the risk of infection.

### How many muscles are needed to make your foot move?

• A.

5

• B.

35

• C.

20

• D.

116

• E.

21

C. 20
Explanation
The foot is composed of multiple muscles that work together to enable movement. While there are more than 20 muscles in the foot, the question likely refers to the main muscles responsible for foot movement. These include muscles in the lower leg, such as the gastrocnemius and soleus muscles, as well as muscles in the foot itself, like the flexor hallucis longus and extensor digitorum longus. Therefore, 20 is a reasonable estimate for the number of muscles needed to make the foot move.

### A callus is the thickened skin on the foot.

• A.

True

• B.

False

A. True
Explanation
A callus is a common condition where the skin on the foot becomes thick and hardened due to repeated friction or pressure. It is typically caused by wearing ill-fitting shoes or engaging in activities that put excessive pressure on the feet. The thickened skin forms as a protective response to prevent further damage to the underlying tissues. Therefore, it is true that a callus is the thickened skin on the foot.
