Which directional term is used to describe the relationship of the skin to the skeletal muscles? lateral superficial deep medial

Superficial The skin covers the outside of the body; thus, it is superficial, or external, to the skeletal muscles.

The term pollex refers to the ________. fingers calf great toe thumb

thumb

Match the words in the left column to the appropriate blanks in the sentences on the right. 1. : Arm. 2. : Buttock. 3. : Head. 4. : Knee (anterior aspect). 5. : Chest.

1. Brachial 2. Gluteal 3. Cephalic 4. Patellar 5. Thoracic

Which of the following is the proper description of the human body in the anatomical position? 1. The body is erect with feet slightly apart and palms facing forward with thumbs pointing away from the body. 2. The body is erect with feet together, palms facing backward, and thumbs pointing toward the body. 3. The body is erect with feet slightly apart and arms extending perpendicular to the torso along a straight line with the clavicle. 4. The body is erect with feet together and palms facing the thighs with thumbs pointing forward.

1. The body is erect with feet slightly apart and palms facing forward with thumbs pointing away from the body. In the anatomical position, the body is erect with feet slightly apart and arms at the sides. This position is easy to remember because it resembles "standing at attention," except that the palms face forward and the thumbs point away from the body.

The knee is proximal to the thigh. True False

False Proximal means closer to the origin of the body part or the point of attachment of a limb to the body trunk. Distal means farther from the origin of a body part or the point of attachment of a limb to the body trunk. In this case, because the thigh is closer to the body trunk than the knee, the knee is distal (not proximal) to the thigh.

The serous membrane is a double-layered membrane created by two separate membranes. True False

False The serous membrane is a double-layered membrane that has folded back on itself.

Choose the following statement that is not completely correct regarding serous membranes. Serosa are very thin, double-layered structures. Serous membranes are divided into parietal and visceral membranes with a virtual space between the two. Visceral pericardium covers the outer surface of the heart, and parietal pericardium lines the internal walls of the heart. Serous membranes secrete a watery lubricating fluid.

Visceral pericardium covers the outer surface of the heart, and parietal pericardium lines the internal walls of the heart.

Which of the following describes a parasagittal plane? any sagittal plane except in the midline any cut dividing the body into anterior and posterior portions a transverse cut just above the knees two cuts dividing the body into left and right halves

any sagittal plane except in the midline

Which of the following is the regional term that includes the head? superior appendicular axial coronal

axial

What is a vertical section through the body, dividing it into anterior and posterior regions called? sagittal median frontal transverse

frontal

The thoracic cavity contains the ________. It is found ________ to the vertebral cavity. stomach and liver: superficial kidneys and spleen: deep heart and lungs: anterior digestive viscera: inferior

heart and lungs: anterior

You are told to take an axillary temperature on a small child. You will place the thermometer ________. under the tongue in the armpit in the rectum on the forehead

in the armpit

In which quadrant of the abdominopelvic cavity is the stomach located? left lower quadrant left upper quadrant right lower quadrant right upper quadrant

left upper quadrant

The parietal pleura would represent a serous membrane ________. lining the abdominal cavity covering individual lungs covering the heart lining the thoracic cavity

lining the thoracic cavity

What is a vertical section through the body, dividing it into left and right, called? frontal transverse regional sagittal

sagittal

The dorsal body cavity is divided into which of the following subdivisions? the vertebral/spinal, cranial, and pleural cavities the vertebral/spinal and thoracic cavities the thoracic, pleural, and abdominopelvic cavities the vertebral/spinal and cranial cavities

the vertebral/spinal and cranial cavities The dorsal body cavity, which protects the fragile nervous system organs, has two subdivisions: the cranial cavity and the vertebral, or spinal, cavity.

Which body cavity is further separated into other cavities? abdominopelvic pericardial pleural thoracic

thoracic The thoracic cavity contains the pericardial and pleural cavities, which in turn house the heart and lungs, respectively.

Anatomical position is important because ________. 1. it allows a common point of reference for body position to help communicate anatomical relationships 2. it is the position most comfortable to hospital patients 3. it allows diagrams within textbooks to display a greater surface area of the body with one simple diagram 4. it provides the greatest circulation to the extremities

1. it allows a common point of reference for body position to help communicate anatomical relationships

Which of these is not part of the ventral cavity? thoracic cavity abdominal cavity abdominopelvic cavity vertebral cavity

vertebral cavity

The part of the serous membrane that lines the peritoneal cavity wall is called visceral peritoneum. True False

False

Which of the following organs or structures would be found in the left iliac region? intestines liver appendix stomach

intestines

The right hypochondriac region contains the majority of the stomach. True False

False

A coronal section creates a superior and an inferior section. True False

False A transverse section creates a superior and an inferior section.

Which of the following statements is correct? The sternum is dorsal to the spine. The heart is posterior to the spine. The sternum is posterior to the spine. The heart is dorsal to the sternum.

The heart is dorsal to the sternum. The heart is dorsal (posterior) to the sternum. In humans, the terms dorsal and posterior are synonymous with one another, meaning "toward or at the back of the body," or behind.

What is the role of the serous membranes covering some organs? to serve as extra tissue for blood flow to the organ to provide a protective outer covering for the organ to provide passage of nutrients for the organ tissues to prevent friction between the organ and body cavity wall

to prevent friction between the organ and body cavity wall The two serous membrane layers are separated by a cavity containing serous fluid. This fluid allows organs to slide without friction across the cavity walls and one another as they carry out their routine functions.

What is the mediastinum?

The mediastinum is a cavity contained within the thoracic cavity.

Which of the following cuts could cross the umbilical, pelvic, and nasal regions? oblique section coronal section sagittal section transverse section

Sagittal A sagittal section is a cut made through the sagittal plane--a vertical plane that divides the body into right and left parts. A midsagittal section would cross the nasal, umbilical, and pelvic regions.

The epigastric region is superior to the umbilical region. True False

True
