Which of the following structures should be visualized through the foramen magnum in an ap axial projection (towne method) of the skull for occipital bone?
1. posterior clinoid processes2. dorsum sella3. posterior arch of c1a. 1 onlyb. 2 onlyc. 1 and 2 onlyd. 2 and 3 only

The correct option is C: Posterior clinoid processes and dorsum sellae.

Explanation:

An Anteroposterior (AP) axial projection (Towne method) is a radiograph of the skull used to evaluate and demonstrate the presence or state of fractures.

Structures that can be seen are the entire occipital bone, the petrous part of the pyramids, and the foramen magnum. Through this last one, there can be seen the dorsum sellae and the posterior clinoid processes.  

im gonna compare the cells to jobs in factory. give brainliest

job in the factory //       cell organelle   //  

shipping/receiving

department                 plasma membrane    

chief executive officer// nucleus

factory floor // cytoplasm

assembly line// endoplasmic reticulum

workers in the assembly line //ribosomes

finishing/packaging department //golgi apparatus

maintenance crew //lysosomes

support beams (walls, ceilings, floors) //cytoskeleton

power plant //mitochondria/chloroplasts

here's what each part of the cell does:

plasma membrane :

regulates what enters and leaves the cell; where cell makes contact with the external environment

nucleus :

controls all cell activity; determines what proteins will be made

cytoplasm :

contains the organelles; site of most cell activity

endoplasmic reticulum:

where ribosomes do their work

ribosomes :

build the proteins

golgi apparatus :

prepares proteins for use or export

lysosomes :

responsible for breaking down and absorbing materials taken in by the cell

cytoskeleton :

maintains cell shape

mitochondria/chloroplasts :

transforms one form of energy into another
