Human Anatomy and Physiology Midterm Quiz

What are the five functions of the skeletal system?

• Support, flexibility, digestion, energy production, and waste elimination

• Support, protection, movement, storage, and blood cell production

• Protection, communication, reproduction, nutrient absorption, and hormone regulation

• Movement, insulation, sensory perception, waste removal, and muscle coordination

Explain the difference between compact and spongy bone.

• Compact bone is dense and hard, while spongy bone is less dense and has many small holes filled with red bone marrow.

• Compact bone is soft and flexible, while spongy bone is hard and rigid.

• Compact bone is less dense and has many small holes filled with red bone marrow, while spongy bone is dense and hard.

• Compact bone is found in the ends of long bones, while spongy bone is found in the shafts of long bones.

How do muscles work in pairs to move the body?

• By stretching and compressing to produce movement

• By inflating and deflating to produce movement

• By expanding and contracting to produce movement

• By contracting and relaxing to produce movement

Describe the structure and function of the three types of muscle tissue.

• Skeletal, cardiac, and smooth muscle tissues have different structures and functions.

• Bicep, tricep, quadricep muscles are the three types of muscle tissue

• Muscle tissue is all the same and has no different structures or functions

• The three types of muscle tissue are named after the body parts they are located in

What are the three main functions of the nervous system?

• Vision, hearing, and taste

• Memory, learning, and emotions

• Sensory input, integration, and motor output

• Digestion, respiration, and circulation

Explain the difference between the central nervous system and the peripheral nervous system.

• The central nervous system is located in the arms and legs, while the peripheral nervous system is located in the head and torso.

• The central nervous system is responsible for motor functions, while the peripheral nervous system is responsible for sensory functions.

• The central nervous system is made up of the autonomic nervous system, while the peripheral nervous system is made up of the somatic nervous system.

• The central nervous system consists of the brain and spinal cord, while the peripheral nervous system includes all the nerves outside of the central nervous system.

What are the functions of the integumentary system?

• Protection, sensation, temperature regulation, vitamin D production, and excretion

• Hormone production and regulation

• Muscle movement and coordination

• Digestion, respiration, and circulation

Describe the structure and function of the epidermis and dermis layers of the skin.

• The epidermis is the outermost layer of the skin, providing a waterproof barrier and creating our skin tone. The dermis is the layer beneath the epidermis that contains tough connective tissue, hair follicles, and sweat glands.

• The epidermis is a layer of bone tissue in the skin, providing structure and support. The dermis is a layer of blood vessels and nerves that supply nutrients and sensation to the skin.

• The epidermis is the innermost layer of the skin, providing a waterproof barrier and creating our skin tone. The dermis is the outermost layer that contains tough connective tissue, hair follicles, and sweat glands.

• The epidermis is a layer of muscle tissue in the skin, providing flexibility and movement. The dermis is a layer of fat tissue that insulates the body and stores energy.

What are the five special senses and their corresponding sensory organs?

• The five special senses are hunger, thirst, fatigue, vision, and hearing. Their corresponding sensory organs are the stomach, mouth, muscles, eyes, and ears.

• The five special senses are sight, hearing, taste, smell, and touch. Their corresponding sensory organs are the eyes, ears, tongue, nose, and skin.

• The five special senses are balance, temperature, pressure, vision, and sound. Their corresponding sensory organs are the inner ear, skin, muscles, eyes, and ears.

• The five special senses are taste, touch, smell, sight, and hearing. Their corresponding sensory organs are the mouth, skin, nose, eyes, and ears.

Explain how the process of vision occurs in the eye.

• Light enters the eye through the ear canal and is converted into sound waves

• The process of vision occurs in the nose, where the sense of smell is also located

• The eye captures images by emitting light from the retina

• Light enters the eye through the cornea, passes through the pupil, and is focused by the lens onto the retina. The retina then converts the light into electrical signals that are sent to the brain via the optic nerve.
