Endocrine System (Hormones in Animals/WBBSE))RanjanShaw5
ENDOCRINE SYSTEM : Endocrine system is the system formed by ductless glands which secrete chemical substances called as hormones. Endocrine glands release hormones directly into the blood.
Hormones are minute, chemical messengers thrown into blood to act on target organs.
Hormones can be steroids, proteins, peptides or amino acid derivatives.
These hormones act as on specific organs called target organ.
The target cell has on it surface or cytoplasm, a specific protein molecule called receptor.
The receptor can recognise and pick out the specific hormone capable of acting in cell.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

1.
2. It helps you cope with changes in your environment.
It works with the NS, RS and other organs such as
kidney, gut and pancreas to help maintain and
control body energy levels, reproduction, growth
and development, responses to stimuli and stress
and internal balance.
Gland is an
organ that
produces a
secretion for use
elsewhere in the
body, or in a
3. Exocrine Gland the
secretions pass through a
duct to the site where they
take effect. Ex: salivary,
sweat and mammary
glands.
Endocrine Gland ductless
because they secrete their
product directly into the
bloodstream.
Hormones a chemical
messenger that transports a
signal from one cell to
another. “Target cells”,
4. ENDOCRINE GLANDS
1.) Pituitary Gland master of the ductless glands;
aka hypophysis, lies at the base of the brain.
a.) Oxytocin responsible for contraction of the
uterine muscles during the final stage of pregnancy.
b.) Vasopressin
increases
blood pressure
and decreases
urine flow; aka
antidiuretic
hormone (ADH).
5. c.) Growth Hormone aka somatotropic hormone -
essential for normal growth.
d.) Adrenocorticotropic Hormone (ACTH) controls
the adrenal glands that takes part during emergency
or stressful situation.
e.) Prolactin initiates milk production.
f.) Luteinizing Hormone (LH) stimulates the
formation of ovarian hormones and the subsequent
release of a mature egg.
g.) Follicle Stimulating Hormone (FSH) responsible
for the formation of follicles around an egg in the
female ovary and the development of sperm in males.
6. 2.) Thyroid Gland H-shaped organ; beneath the
larynx.
a.) Thyroxin(e) controls the body’s metabolism;
aka tetraiodothyronine (T4).
It increases the oxygen consumption, or speeds up
the metabolic rate of nearly all the cells in the body
except the brain, spleen and testes.
Sometimes the
gland may be
hyperactive
(hyperthyroidine)
or underactive
(hypothyroidine).
7. Cretinism physically and mentally retardation
due to failed development of the thyroid gland.
8. Without a sufficient supply of iodine, all body cells
will work harder; this eventually results in swelling
of the thyroid, a condition commonly known as
goiter.
9. b.) Calcitonin aka triiodothyronine (T3); storage of
Ca and P balance in the blood plasma and bones.
It takes Ca and P ions from bones so that they will
be available in the blood, the muscles and nerves.
10. 3.) Parathyroid Gland 4 small glandular bodies,
each about the size of a small pea, attached to the
back of the thyroid gland.
a.) Parathyroid hormone or Parathormone controls
the Ca levels in your body and normalizes bone
growth.
It takes Ca
and P ions
from bones so
that they will
be available in
the blood, the
muscles and
11. 4.) Thymus Gland 2 lobes located at the upper part
of the chest, below the neck.
Quite prominent in early life, buy degenerates
when puberty sets in then it will be replaced by a
fatty or fibrous tissue.
a.) Thymosin – it
manufactures WBC and
antibodies that make it
possible to develop
immunity against
infection.
b.) Promine – promotes
growth
c.) Retine – retards growth
12. 5.) Adrenal Glands small glands above each
kidneys.
a.) Adrenal Cortex – outer portion; secretes
corticoids.
Regulate the metabolism – storage and use of
proteins, fats and carbohydrates.
Control the amount of water, which the body
retains or excretes.
Monitor the levels of important body salts.
Influence growth and development
Control the production of blood cells and also the
formation of the skin color.
13. b.) Adrenal Medulla – inner portion; secretes
adrenalin.
Aka epinephrine, secreted during times of
excitement, anger, stress, pain or cold.
It raises the blood pressure and increases the
heartbeat and the body temperature.
Brings about the widening of the blood vessels in
the liver, heart and skeletal muscles.
It promotes the conversion of sugar in the body,
making it more available for your energy needs.
14. Noradrenalin or norepinephrine, which functions in
the same way that adrenalin does; it supplements the
action and complex functions of the nervous system.
15. 6.) Pancreas between the kidneys; hormone-
secreting cells are found in the islet of Langerhans.
a.) Glucagon
– it converts
glycogen
(stored body
sugar in the
liver) to
glucose when
your blood
glucose
concentration
16. b.) Insulin – controls the storage of sugar in the liver
and the sugar breakdown in the tissues.
Diabetes mellitus, a
disease in w/c the
pancreas produces
insufficient insulin or in
w/c the body’s cells fail
to respond correctly to
insulin.
Diabetes insipidus,
there is an excretion of
large amounts of
diluted urine that
cannot be further
17. 7.) Male Gonads lower abdomen
a.) Testes – secretes androgen and testosterone;
control maturation and male characteristics
Prostate Gland –
produces a thin,
watery, alkaline
secretion that mixes
with the sperm and
other secretions to
form the semen.
Cowper’s Gland
(Bulbourethral) – add fluids
and protection to semen
during the process of
18. 7.) Female Gonads lower abdomen
b.) Ovaries – secretes estrogen and progesterone;
influence female traits and support reproductive
function
