Quiz 10 + 11 guide + Endocrine: lab preview

Quiz 10 + 11 guide
For quiz 10 there will be identification questions from sheep brain, brain model, cow eye, eye model, ear model, slides.
For theory please follow the CNS, eye, ear etc etc lab preview notes which seems to be extensive. Click on this link: CNS,eye,ear,stretch reflex: lab preview Feel free to e-mail me if you have any doubts of CNS etc etc lab.
Also we shall be having another quiz (Quiz 11) from last lab of Endocrine . This will be open book.

Endocrine: lab preview
Main focus of this lab is anatomy, histology and regulatory functions of different endocrine organs.
Though the quiz will be open book, I personally think there is lot of information in this lab that you need to remember. Especially the histological section (you have lots of slides).

Couple of experiments that we will be doing:
1) Study of Antidiuretic hormone (ADH): Use frogs for this purpose. Since ADH assists in water reabsorption, the frog that has been injected with ADH will weigh more if kept in water. This can be known by weighing frog at 0 hr and then on at 30 minutes interval for two hours.

2) Role of Thyroid hormones: We will be demonstrating this in mice that are either normal, hypothyroid, or hyperthyroid and measuring their rate of oxygen consumption in Scholander respirometer. Decide which group wants what kind of mice. Group with hyperthyroid mice needs to take extra care of mice.

3) Oxytocin induced milk release: We will not be able to do this experiment as females failed to get pregnant however you need to know the theory behind this experiment.

HURRAY END OF LABS.

NOTE + Quiz 9 guide + CNS,eye,ear,stretch reflex: lab preview+ grades

NOTE
I shall not be teaching this weeks lab. Liz will be coming to teach you
Make sure one member from each group wears short so that you can perfom stretch reflex experiment

Quiz 9 guide
- Comparison between SAP and CAP
- How can CAP be applied to clinical applications
- Program used for SAP and the results obtained
- How and why were alpha and beta peaks different when recorded?
- What is the threshold stimulus, conduction velocity and latency
- Refractory periods both relative and absolute
- Different kind of graphs that you got as results

CNS,eye,ear,stretch reflex: lab preview
In this lab we again identify few specimens: You will be given sheep brain structures on it, cow eye & we will have an ear model for stucture identification. Either of these will be kept in final exam for structure identification.

Sheep brain: Pages 95-97 Atlas
Cranial nerves: Page 91, fig 9.11 Atlas

Two ways to remember names of cranial nerves:

Spinal cord: Can be divided into White matter and Gray matter.
-White matter consists of myelinated fibers
-Gray matter consists of cell bodies, dendrites and unmyelinated fibers which are subdivided into dorsal horns and ventral horns. Know function of dorsal and ventral horns.
-Identification of spinal cord model and slides of cerebellar cortex(cerebellum), cerebral cortex, spinal cord.
-Different cell types: Neruons and glia(different kinds of glial cells).
-Neurochemistry: Slides specific for different neurotransmitters

Eye:
Cow eye dissection
Do the blind spot test

Ear:
Model of ear
Do the test with audiometer

Other test of senses:
Two point discrimination

Mechanoreceptor study:
You will also be given cockroach leg with an aim to understand the sensory
mechanoreceptors. Try comparing this with hairs on your hand.

Stretch reflex:
Here you will try study the myotactic or stretch reflex. When you hit your knee with hammer, sensory neuron will transmit information to spinal cord. Spinal cord generates response which is passed onto motor neurons and you can see kicking of your leg (reflex). We will be using this knee-jerk response model to study myotactic reflex.
