Match each of the following skull features with its correct bone. a. styloid process
b. infraorbital foramen
c. sella turcica
d. foramen magnum
e. coronoid process
f. crista galli

1. ethmoid bone
2. sphenoid bone
3. temporal bone
4. mandible
5. maxilla
6. occipital bone

The left column contains structures of the bones that belong to the right column.

a) styloid process - 3) temporal bone

b) infraorbital foramen - 5) maxilla

c) sella turcica - 2) sphenoid bone

d) foramen magnum - 6) occipital bone

e) coronoid process - 4) mandible

f) Crista galli - 1) ethmoid bone

Explanation:

The inferior part of the petrous temporal bone forms the styloid process that allows the stylohyoid, stylopharyngeus, and styloglossus muscles to attach with styloid ligaments.

The infraorbital foramen is the opening of the maxillary bone of the skull

sella turcica is a saddle-like structure in the body of the sphenoid bone of the skull.

The foramen magnum is the lower part of the cranial  foss that allows the connecting brain and spinal cord and it the opening

The coronoid process is shoulder joint as well and required mandibles in the skull to form.

Crista galli arises from ethmoid bone that is thick and midline triangular but smooth process.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
