Chapter 1 Mastering A&P Bio

Mrs. Nguyen was sitting in the front passenger seat and hit her head on the windshield. Doctors suspect internal bleeding, which could be putting pressure on her brain. Which of the following medical imaging techniques would be best for quickly locating any bleeding?

CT

Your neck is known as the region.

Cervical

The lateral side of your leg is called the region and includes the bone called the fibula.

Fibular

The region of the back is low and just lateral to the lumbar vertebrae.

Lumbar

When you rest your elbows on a table, you are resting on the region.

Olecranal

The heart is surrounded by the

Pericardium

The is a membrane that surrounds and suspends organs within the abdominal cavity.

Peritoneum

The lungs and heart are housed within the

Thoracic cavity

The portion of serous membrane that covers the outer portion of an organ is the

Visceral serosa

Bones lie __________ to muscles.

deep

functional morphology

functional morphology This branch of anatomy explores how organs and body structures work and assesses the efficiency of their design.

Identify the membranes that line the cavity surrounding the lungs.

parietal and visceral pleura

Urinary System

regulates water, electrolyte, and acid-base balance of the blood

Integumentary System

synthesizes vitamin D

The _____ is the proximal region of the lower limb.

thigh

The proximal convoluted tubule is a structure within the kidney nephron that plays a significant role in the reabsorption of important products that have been filtered from the blood. One of the key features of this structure is its lining. The cells that line the tubule are responsible for the transport of substances across the membrane. These cells and their collective efforts would be an example of which of the following levels?

tissue level

The doctor tells Mr. Nguyen that there is a break to one of the vertebrae in the cervical region of his vertebral column. He is surprised to hear this, as he can move all of his body parts just fine. Why might a break to a cervical vertebrae not necessarily result in paralysis?

The vertebral column is made up of vertebrae. A force that is strong enough to damage vertebrae may not necessarily damage the spinal cord.

Which of the following is true regarding the anatomical position?

Directional terminology refers to the body in this position.

A single lung is contained within a

Pleural cavity

The back portion of your knee is called the region.

Popliteal

Skeletal system

Produces blood cells

Muscular System

Produces heat

The body region containing the axillary, sternal, and mammary regions is the _____.

thorax

The __________ region of the body consists of the head and trunk.

axial

Which of the following would be considered to be part of the thoracic region? Select all that apply

axillary, mammary, and sternal region

The right nostril and right ear are __________.

ipsilateral

Respiratory System

keeps blood constantly supplied with oxygen

Which advanced imaging technique is capable of distinguishing body tissues on the basis of differences in water content, and makes bones "invisible"?

magnetic resonance imaging (MRI)

The sternal region is __________ to the axillary region.

medial

Cardiovascular System

transports blood, which carries oxygen, carbon dioxide, nutrients, and wastes

The dorsal body cavity is completely encased in bone and includes the cranial cavity housing the brain as well as the , which houses the spinal cord.

Vertebral cavity

Embryology

Embryology

Golgi apparatus, mitochondria, and other organelles compartmentalized into a single structure by phospholipids, forming a single functional unit

cellular level

When many molecules come together to form organelles that become compartmentalized into a single structure that works as a unit, you have an example of the

cellular level

Which of the following terms indicates the neck region?

cervical

Carbon, hydrogen, and phosphate coming together to form the phospholipids of a cellular membrane

chemical level

Oxygen and hydrogen combine with one another to form water; this is an example of the of organization.

chemical level

Your ankle contains a set of bones that share the same name as this region, which is the region.

Tarsal

radiographic anatomy

This branch of anatomy studies internal body structures by means of MRI, sonography, and other imaging techniques.

gross anatomy

This is the study of body structures that can be examined with the naked eye-bones, lungs, and muscles for example.

histology

This is the study of microscopic structures including cells, tissues, and microscopic details of organs.

surface anatomy

This is the study of shapes and landmarks that reveal underlying organs.

What is the advantage of functional magnetic resonance imaging (fMRI) over positron emission tomography (PET)?

fMRI pinpoints smaller brain areas, does not use radioactive tracers, and works faster.

The inguinal region is located _____ to the umbilical region.

inferior

Cardiac muscle, connective tissue, and endothelial cells all collecting together to form the human heart (what level)

organ level

The small intestine contains epithelial tissue, muscle tissue, and nervous tissue. The combination of these different tissue types to form one discrete structure is an example of the

organ level

The tibia, which is made of connective tissue and nervous tissue

organ level

The pituitary gland, adrenal gland, and other hormone-producing organs all work together to help the body send hormones through the blood stream and respond to internal changes. This is an example of the

organ system level

Patients with appendicitis often complain of abdominal pain in the right lower abdominopelvic quadrant. The appendix itself is in the__________.

right iliac region

Which of the following best represents an example at the organ level?

stomach

A thin layer of cells that collectively form the lining of the lungs to allow for the diffusion of gases

tissue level

Muscle fibers are cells that contain actin, myosin, and other accessory proteins. When these cells are collected together, they can all function as a unit, carrying out the shortening capabilities of muscle. When multiple cells with a similar function come together, it is an example of the

tissue level

Which of the following organs might have been damaged by the lap seatbelts? Select all that apply.

urinary bladder and small intestine
