Q

A

Rostral

17
Q
  1. Are hypothetical planes used to transect or divide the body
A

Anatomical Planes

18
Q
  1. Three (3) principle planes used in anatomy
A

Sagittal/Median Plane, Frontal/Coronal Plane, Transverse Plane/Cross Section

19
Q
  1. Divides the body into left and right sides
A

Sagittal/Median Plane

20
Q
  1. The sagittal plane is directly on the median line of the body, dividing the body into equal left and right sides
A

Midsagittal

21
Q
  1. The sagittal plane is not on the median line, but is parallel to it. The body is divided into unequal left and right sides
A

Parasagittal

22
Q
  1. Divides the body into front and back / dorsal and ventral sides
A

Frontal / Coronal Plane

23
Q
  1. Divides the body into cranial and caudal parts (superior or inferior parts); or any plane that cuts vertically across the body at right angles to the sagittal plane
A

Transverse Plane / Cross Section

24
Q
  1. No symmetry, no definite form, or the body cannot be divided by planes into similar parts
A

Asymmetrical

25
Q
  1. Ball-like; can be divided into 2 similar parts by a cut in any direction through the center
A

Spherical Symmetry

26
Q
  1. A number of planes can be drawn through the center, dividing the body into many equal parts. The animal possesses a number of similar parts (called antimeres), which radiate out from a central axis
A

Radial Symmetry

27
Q
  1. refers to the center axis of the organism
A

Central

28
Q
  1. refers to the side of the radial animal where the mouth is located
A

Oral side

29
Q
  1. refers to the side of the radial animal opposite to the oral side
A

Aboral side

30
Q
  1. There is only one plane through which the body can be divided into 2 equal parts (left and right)
A

Bilateral Symmetry

31
Q
  1. The animal is so well-constructed that some organs are also arranged in pairs on either side of the axis
A

Bilateral Symmetry

32
Q
  1. Bilateral animals are the only ones that display
A

Cephalization

33
Q
  1. They possess a head which contain the chief nervous organ and main sense organs
A

Cephalization

34
Q
  1. Which is the repetition of structural subunits when the body is composed of more or less similar parts (each subunit/part is called a metamere or segment)
A

Metamerism

35
Q
  1. External and internal structures divided into similar units
A

Homologous segmentations

36
Q
  1. Animals that are divided into unequal segments/metameres
A

Heteronomous segmentation

36
Q
  1. External and internal structures divided into similar units
A

Homologous segmentations
