What is this
Function?
Tissue bath
An organ chamber, organ bath, or isolated tissue bath is a chamber in which isolated organs or tissues can be administered with drugs, or stimulated electrically, in order to measure their function- maintains the integrity of the organ/ tissue
Connecting tube of the spirometer
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
Decorticate posture
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.
What is this
Function ?
Wright peak flow meter
Used to measure peak expiratory flow rate —
The PEFR is the amount of air a person can quickly force out of their lungs in one breath.
Describe with function
Douglas bag -used to carry expired air
inflatable bag used to collect expired air for the determination of oxygen consumption and basal metabolic rate. Made of tough, polyvinyl chloride and have electrically welded seams, they are lighter and more flexible than rubber bags and less gas permeable, to minimise measurement errors
Nose clips -used to hold nose during respiratory experiments
Soda lime cannister -used to absorb co2
Changes colour when it reaches maximum capacity

What is the function?
Conway dish
glassware used for micro diffusion experiments
Ovarian cycle
Exopthalmos - seen in Graves’ disease
Goiter swelling
Body mass index
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.
Lancets -used to Prick the finger while measuring blood glucose levels
To draw little blood
What is this ?
Function ?
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).
What is this ?
Glucometer -used to measure blood glucose levels
A blood glucose meter is a small, portable machine that’s used to measure how much glucose (a type of sugar) is in the blood (also known as the blood glucose level). People with diabetes often use a blood glucose meter to help them manage their condition.
Describe this ?
Ishihara chart. Used to test for colour blindness
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.
What is this ?
Snellens chart -used to test visual acuity
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.

What test is this for ?
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.
Ophthalmoscope-used to view interior of the eye, observe retina and the arteries
What is this ?
What is it used for ?
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
Anesthesiometer -used to measure two point discrimination and touch sensation
