What are the microscopes used in lab called?

compound microscopes

what are oculars

eye pieces on microscope, they have a 10x occular magnification, one of the occulars may contain a micrometer

objective lens

The magnification of objective lenses ranges from 4x to 100x,

condenser

Located just below the stage is a lens that condenses light through the specimen on the slide above

what should u only use to clean the microscope?

lens paper

stratified cuboidal

what type of tissue is this

psudostratified columnar epithelium

what type of tissue is this

stratified squamous

what type of tissue is that

spongy bone

masseter

closes mouth: aids in chewing

temporalis

closes mouth: pulls lower jaw into upper jaw

medial pterygoid

Closes mouth; pushes lower jaw out under upper jaw; moves lower jaw side-to-side

how do you calculate total mag?

occulars x mag

Lateral pterygoid

Opens mouth; pushes lower jaw out under upper jaw; moves lower jaw side-to-side (YAWN)

Sternocleidomastoid

If one side is contracted, rotates/tilts head sideways – "obliques" skull – tilt same side/turn opposite side; if both sides contracted, draws head forward and down; flexes neck 

Digastricus

Open mouth (lowers mandible), elevates and holds hyoid during speech and swallowing

trapezius

Elevates, depresses, and retracts scapula, both acting together, draw head dorsally (backward)

latissimus dorsi

Adducts and extends shoulder (humerus), rotates shoulder (humerus), draws shoulder down and backward

pectoralis major

Flexion, adduction and medial rotation of shoulder (humerus)
