Animal Review

Body parts extend from the center, any number of imaginary planes drawn through the center results in equal halves

• bilateral symmetry

• radial symmetry

• asymmetry

Answer explanation

Body parts extend from the center, any number of imaginary planes drawn through the center results in equal halves, indicating radial symmetry.

A single imaginary plane divides the body into left and right halves. Defined front/anterior, end, back/posterior, dorsal, ventral sides.

• bilateral symmetry

• radial symmetry

• asymmetry

Answer explanation

The correct choice is bilateral symmetry because it involves a single imaginary plane dividing the body into left and right halves, with defined front, back, dorsal, and ventral sides.

body plan is not symmetrical (e.g. sponge)

• bilateral symmetry

• radial symmetry

• asymmetry

Answer explanation

The correct choice is 'asymmetry' because a body plan that is not symmetrical, like a sponge, is considered asymmetrical.

Anatomical term for above

• superior

• inferior

• ventral

• anterior

• posterior

Answer explanation

The anatomical term for 'above' is 'superior', which refers to a position closer to the head or upper part of the body.

Anatomical term for below

• superior

• inferior

• ventral

• anterior

• posterior

Answer explanation

The anatomical term for 'below' is 'inferior' in reference to the position of a body part in relation to another part.

Anatomical term for front

• superior

• inferior

• ventral

• anterior

• posterior

Answer explanation

The anatomical term for front is 'anterior' or 'ventral'. These terms refer to the front side of the body in anatomical positions.

Anatomical term for back

• superior

• inferior

• dorsal

• anterior

• posterior

Answer explanation

The anatomical term for 'back' is 'posterior' or 'dorsal', referring to the rear or upper side of the body.

Anatomical term for close to trunk

• proximal

• distal

• superficial

• deep

• lateral

Answer explanation

The anatomical term for 'close to trunk' is proximal, which refers to a position closer to the point of attachment or origin.

Anatomical term for far away from trunk

• proximal

• distal

• superficial

• deep

• lateral

Answer explanation

The anatomical term for far away from the trunk is 'distal'. Distal refers to a position farther away from the center of the body or the point of attachment.

Anatomical term for near surface

• proximal

• distal

• superficial

• deep

• lateral

Answer explanation

The correct anatomical term for near the surface is 'superficial' as it refers to structures closer to the surface of the body.
