Chapter 13, Problem 1WYL
Identify at least two surface features of the orbital region that protect the eye.
Expert Solution & Answer
Summary Introduction
To determine:
The surface features of the orbital region that is responsible for the protection of the eye.
Introduction:
The human face is divided into five different regions. These regions are auricular, orbital, nasal, oral, and mental. The region which includes eye and its related structures is known as orbital region.
Explanation of Solution
Most of the surface features of the orbital region are responsible for protecting the eye. There are three surface features of the orbital region. These features are as follows:
• Eyelids:
The function of eyelids is to protect the eyes against any object moving near the eye. It also prevents contact of airborne particles with the eyeball.
• Eyebrows:
They are responsible for protecting the eyes from sunlight and any possible mechanical damage to the eye.
• Superior palpebral fissure:
It is also known as upper eyelid crease. Most individuals can easily touch it. It also protects the eye.

Your percent intake compared to the RDA/DRI (example “I consumed 50% of the RDA for vitamin D”)
Indicate why your intake was below the recommendations (example: “I only had one serving of dairy products and that was why I was below the recommendations for vitamin D”)

Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply. Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.arrow_forwardWhen physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well. From the list below, choose all the correct statements about the effects of increased physical activity or athletic training. Select all that apply. An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day. How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity. Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake. Athletes who are following energy-restricted diets are at risk for consuming insufficient protein. The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.arrow_forward
