Decerebrate rigidity

Also known as extensor posturing, decerebrate rigidity is a term that describes the involuntary extensor positioning of the arms, flexion of the hands, with knee extension and plantar flexion when stimulated as a result of a midbrain lesion-upper brainstem

Q

Decorticate posture

A

While decorticate posturing is still an ominous sign of severe brain damage, decerebrate posturing is usually indicative of more severe damage at the rubrospinal tract, and hence, the red nucleus is also involved, indicating a lesion lower in the brainstem.

Q

Body mass index

A

Body mass index is a value derived from the mass and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m², resulting from mass in kilograms and height in metres.

Glucose strips
Used to measuring blood glucose levels

Test strips contain a capillary that sucks up a reproducible amount of blood. The glucose in the blood reacts with an enzyme electrode containing glucose oxidase (or dehydrogenase).

The Ishihara test is a color perception test for red-green color deficiencies, the first in a class of successful color vision tests called pseudo-isochromatic plates. It was named after its designer, Shinobu Ishihara, a professor at the University of Tokyo, who first published his tests in 1917.

Snellen chart, also called Snellen eye chart, chart used to measure visual acuity by determining the level of visual detail that a person can discriminate. It was developed by the Dutch ophthalmologist Herman Snellen in 1862 and was adopted by medical professionals in many countries who have used it for more than 100 years.

Perimeter- used to measure visual fields of the eye

A perimetry test (visual field test) measures all areas of your eyesight, including your side, or peripheral, vision. To do the test, you sit and look inside a bowl-shaped instrument called a perimeter. While you stare at the center of the bowl, lights flash.

Tuning fork -use to construe vibrations -vibration experiments

A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs formed from a U-shaped bar of elastic metal. It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out

Q

What test is this used for ?

A

Sahli hemoglobinometer -used to measure hemoglobin levels

It is based on comparison of the color of the tested blood, which is treated with hydrochloric acid, with the color of standards

When blood is treated with a hydrochloric acid solution, the hemoglobin is converted to hematin hydrochloride, and the solution turns brown. The solution in the test tube is diluted by gradually adding distilled water until the color of the solution is the same as that of the standard. The quantity of hemoglobin is determined by reading the level of the solution on the scale of the test tube.

33
Q

What is this instrument?

A

Spirolab/spirometer - used to measure FEV, FVC and lung volumes

A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. A spirometer measures ventilation, the movement of air into and out of the lungs. The spirogram will identify two different types of abnormal ventilation patterns, obstructive and restrictive.

37
Q

What is this ?

A

Centrifuge, colorimeter

A centrifuge is a device that uses centrifugal force to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities or liquids from solids.

38
Q
A

Hematocrit reader -used to measure PCV or hematocrit value

39
Q

Describe this effect

A

Rouleaux effect

The flat surface of the discoid RBCs gives them a large surface area to make contact with and stick to each other; thus forming a rouleau. They occur when the plasma protein concentration is high, and, because of them, the ESR (erythrocyte sedimentation rate) is also increased.

40
Q

A
41
Q

What is refractory period

A

a refractory period is a period of time during which an organ or cell is incapable of repeating a particular action, or (more precisely) the amount of time it takes for an excitable membrane to be ready for a second stimulus once it returns to its resting state following an excitation.
