regions of the upper limb

Acromial Antebrachial Antecubital Axillary Brachial Carpal Digital Metacarpal Pollex

regions of the head a face

Buccal Cranial Frontal Mental Nasal Ocular Oral Otic

rotating nosepiece

Connects the objective lenses to the head and allows different objective lenses to be moved into place.

Regions of the lower and anterior view

Coxal Crural Digital Femoral Hallux Metatarsal Patellar Tarsal

lateral

Farther away from the midline of the body or a body part; on the outer side of ex. the shoulder is lateral to the chest

deep

Farther below the surface ex. bone is deep to the skin

mechanical stage

Flat, horizontal shelf onto which the slide is placed and typically secured with a spring clamp. Two control knobs can be used to move the stage to position the slide.

ocular lense

Lens(es) located within the eyepieces. Monocular microscopes have one ocular lens, whereas bin-ocular microscopes have two ocular lenses. Ocu-lar lenses typically magnify an object 10 times.

iris diaphragm

Located beneath the condenser. Regulates the amount of light that passes through the condenser

substage light

Located in the base. Provides the light that passes through the condenser, the specimen, the lenses, and finally into your eyes. A light control knob lo-cated on the base or the arm controls the bright-ness of the light.

focus knobs

Located on the arm of the microscope just above the base. The larger coarse adjustment knob moves the stage up and down in large increments and is used to find the specimen and for initial focusing; the smaller fine adjustment knob is used for fine focusing after coarse focusing has been completed.

objective lense

Magnifying lenses mounted on a rotating nose-piece. Most microscopes have four objective lenses: scanning (4×), low-power (10×), high-power (40×), and oil-immersion (100×) lenses.

condensor

Small lens located under the stage that con-centrates light onto the specimen. A condenser adjustment knob is used to raise and lower the condenser. The condenser should usually be in its uppermost position, just below the aperture (the hole in the stage through which light travels).

base

The broad, flat, lower part of the microscope that supports the rest of the instrument.

head

The upper part of the microscope that supports the ocular lens(es) and the various objective lenses.

arm

The vertical part of the microscope that connects the head to the base.

medial

closer to the midline of the body or a body part; on the inner side of ex. The ear is medial to the shoulder.

Proximal

closer to the point of origin ex. the knee is proximal to the ankle

superficial

closer to the surface ex. the skin is superficial to the muscle

midsagittal (median) plane

divides the body into equal right and left parts;

parasagittal plane

divides the body into unequal right and left parts.

distal

farther away from the point of origin ex. the foot is distal to the hip

frontal (coronal) plane

is a section made parallel to the body's longitudinal axis; it divides the body into anterior and posterior parts.

sagittal plane

is a section made parallel to the body's longitudinal axis; it divides the body into right and left parts.

transverse plane

is a section made perpendicular to the body's longitudinal axis; it divides the body into superior and inferior parts.

Posterior

toward the back ex. the spinal cord is posterior to the esophagus

anterior

toward the front ex. the palms are on the anterior part of the body

superior (cranial)

toward the head ex. the nose is superior to the mouth

inferior

toward the tail ex. the nose is inferior to the forehead
