A catecholamine is a monoamine, an organic compound that has a catechol (benzene with two hydroxyl side groups at carbons 1 and 2) and a side-chain amine. Included among catecholamines are epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine. Release of the hormones epinephrine and norepinephrine from the adrenal medulla of the adrenal glands is part of the fight-or-flight response.
Testosterone's effects occur through binding to androgen receptors or by aromatization to estradiol. It stimulates protein synthesis in target tissues like the prostate. Gonadotropin-releasing hormone from the hypothalamus stimulates the pituitary to secrete LH and FSH, controlling testosterone and sperm production. Negative feedback loops regulate these processes. Abnormalities can include prostate diseases and hypogonadism.

The nervous system is divided into the central nervous system and peripheral nervous system. The central nervous system consists of the brain and spinal cord and contains gray matter and white matter. The peripheral nervous system is made up of nerves that branch throughout the body. The nervous system detects environmental changes and coordinates the body's actions and sensory information through transmitting signals via neurons. It is composed of neurons, which are the basic functional units, and neuroglia, which provide structure and support. The nervous system functions through nerve impulses that travel along neurons via action potentials and neurotransmitters to transmit signals between neurons.

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.

Dr. Varsha Raj
Pharmacy Academy,
IFTM University, Moradabad
2. Our body is contains two kinds of gland
1. Exocrine gland (with duct) : secrete their product into body duct
ex: sebaceous gland, digestive gland
2. Endocrine gland (without duct): secrete their product (hormones)
directly into the extracellular space around the secretory cell
Hormones are chemical messenger, having the wider variety of effects
and their function, some time it may be sudden or some time may occurs
days later
It maintained the various functions of the body for examples regulate the
body temperature, regulate the homeostasis, maintain trauma, emotional
stress etc.
3. Endocrine system
The endocrine system regulates body activities by the releasing
hormones into blood stream , from where they are carried out through
the whole body
we can study the endocrine gland and their releasing hormones in the
endocrine system and the science of endocrine system is known as
Endocrinology.
The endocrine system is compromising the following endocrine glands:
1. The pituitary gland
2. Thyroid gland
3. Parathyroid gland
4. Adrenal gland
5. Pineal gland
6. Sex gland (gonads)
7. Pancreas
8. Thymus gland
4.
5. The pituitary gland:
• The pituitary gland or hypophysis is attached to the hypothalamus (at
the base of brain)
• The hypothalamus is the connecting link between the nervous system
and endocrine system
• Pituitary gland is also known as master gland of the body
The pituitary gland can be divided in to two parts
1. Anterior pituitary (anterior lobe) (adenohypophysis)
2. Posterior pituitary (posterior lobe) ( neurohypophysis)
6.
7. Anterior pituitary gland releasing hormones:
7 types of hormones
1. Growth hormones (GH)
2. Thyroid stimulating hormone (TSH)
3. Adrenocorticotropic hormone (ACTH)
4. Prolactin hormones (PRL) or luteotropic hormone
5. Luteinizing hormone (LH)
6. Melanocyte-stimulating hormone (MSH)
7. Follicle-stimulating hormone (FSH)
Posterior pituitary gland releasing hormones:
2 type of hormones
1. Anti diuretic hormones (ADH) OR vasopressin
2. Oxytocin
8. Hormones Function
Growth hormones Regulate metabolism, promotes tissue growth specifically
bones and muscles
Thyroid stimulating hormone
(TSH)
Stimulate growth and activity of thyroid gland and
secretion of their hormones
Adrenocorticotropic hormone
(ACTH)
Stimulates the adrenal cortex to secrete the
glucocorticoids
Prolactin (PRL) Stimulates the growth of breast tissue and milk production
Follicle-stimulating hormone
(FSH)
Stimulates the production of sperm and maturation of
ovarian follicles and ovulation
Luteinizing hormone (LH) Stimulate the testosterone and progesterone
Table no .1 Summary of the hormones released by anterior pituitary gland
9. Anterior pituitary gland releasing hormones:
Growth hormones(GH): this is the most abundant hormone
synthesised by the anterior pituitary.
• It stimulates growth and division of most body cells specially bones
and skeletal muscles
• It release is stimulated by the growth hormone releasing hormone
(GHRH)
• Its release is inhibited by the growth hormone release inhibiting
hormone (GHRIH) or somatostatin
• Both stimulated and inhibited hormones are secreted by the
hypothalamus
• Secretion of GH is increase at night during sleep, in cause of
hypoglycaemia ( low blood sugar), exercise, anxiety and peak in
adolescence, decline with age.
Growth hormone deficiency (Hypo) : Dwarfism
Growth hormone excess secretion (Hyper): Acromegaly, gigantism
10. Thyroid hormone: the release of this hormone is stimulated by
thyrotrophin releasing hormone (TRH) from the hypothalamus
Basically there are two type of hormones released by thyroid gland,
Iodine is essential for the formation of this hormone.
T3 : Tri-iodothyronine
T4 : Thyroxine
Both T3 and T4 are essential for normal growth and development of
the whole body, specifically nervous system and skeleton system
Thyroid hormone deficiency : Hypothyroidism (goitre)
Excess concentration of thyroid hormone : Grave’s disease
11. Adrenocorticotropic hormone (ACTH): Corticotrophin releasing
hormone (CRH) promotes the synthesis and releasing of ACTH
This increases the concentration of cholesterol and steroids with
adrenal cortex
ACTH deficiency: (hypoadrenalism) resulting in adrenal hormone
insufficiency
ACTH hyper concentration : Cushing's syndrome
12. Prolactin:
This hormones is stimulated by prolactin releasing hormone (PRH)
It is lowered by prolactin inhibiting hormone (PIH, dopamine)
This hormone is secreted during pregnancy to prepare the breast for
lactation after child birth
13. Gonadotropins : gonadotropins are hormones synthesized and
released by the anterior pituitary, which act on the gonads (testes and
ovaries) to increase the production of sex hormones and stimulate
production of either sperm or ova.
Rising the level of these hormones at the age of puberty and promote
the mature functioning of reproductive organs in both males and
females
Two main gonadotrpins are :
Follicle stimulating hormone (FSH)
Luteinizing hormones (LH)
14. FSH
In female: secrete the estrogen and progesterone
In male: promote the spermatogenesis
LH
In female: ovulation, progesterone
In male: testosterone secretion
15. Posterior pituitary gland releasing hormones
1. Anti diuretic hormones
(ADH) OR vasopressin:
ADH is made by the hypothalamus
and it is stored in posterior pituitary
gland
ADH have the two primary functions
I. To retain water in body
II. To constrict the blood vessels
Hypo secretion of ADH: Diabetes
insipidus ( excess retention of
water), polyuria
Hyper secretion of ADH: syndrome
of inappropriate ADH
16. 2. Oxytocin
1. It is made by the hypothalamus and it is stored in posterior pituitary
gland
2. It stimulate the contraction of memory gland to produce milk
3. It stimulate the contraction of uterus at the time of child birth
17. Thyroid gland
Thyroid gland is situated in the
neck , in the front of larynx and
below the adam’s apple
It is highly vascular , about 25 g
in weight
The thyroid is a butterfly-shaped
gland , consisting from two
connected lobes
18. Microscopically, the functional unit of the thyroid gland is the
1. Thyroid follicle
2. Follicular cells (thyrocytes)
3. Para follicular cell containing colloid
The thyroid gland secretes three hormones:
The two thyroid hormones : tri-iodothyronine (T3)
thyroxine (T4)
One peptide hormone : calcitonin hormone
The thyroid hormones influence the metabolic rate and protein
synthesis, and in children, growth and development.
Calcitonin play the important role in homeostasis of calcium level
Thyroid hormone deficiency : Hypothyroidism (goitre),
hashimoto’s disorder
Excess concentration of thyroid hormone : Grave’s disease
Calcitonin: osteoclasts (break the bone)
19. Parathyroid gland
There are four small parathyroid
glands, each having the 50 g weight
Parathyroid gland is essential for life
and it secrete the parathyroid
hormone
Its main function is increase the
blood calcium level
Hypo-parathyroidism: rickets,
osteomalacia
Hyperparathyroidism: polyuria,
anorexia
20. Adrenal gland
There are two Adrenal gland or
suprarenal gland
They are about 4 cm long and 3
cm thick
there are two part
1. Outer adrenal cortex
2. Inner adrenal medulla
21. Adrenal cortex
It produce the three hormones
1. Glucocorticoids
2. Mineralocorticoids
3. Sex hormones
These are collecteviely known as
adrenocorticoids
1. Glucocorticoids
Cortisol, corticosterone and
cotisone , these are the main
glucocortcoids
They are essential for life ,
regulating stress and
metabolism
22. It promote the gluconeogenesis and lipolysis
It have the anti-inflammatory action, suppress the immune response,
suppress the wound healing
2. Mineralocorticoids
Aldosterone is the main mineralocorticoids
It maintain the water and electrolyte balance
3. Sex hormones
Sex hormone secreted by adrenal cortex is androgen (male sex
hormones)
Hyposecretion of glucocoticoids and mineralocorticoids: Addison’s
disease
Hypersecretion of glucocoticoids: Cushing’ syndrome
23. Adrenal medulla
It is surrounded by the cortex
It produce the two hormones
adrenaline (80%) ( epinephrine)
noradrenaline (20%) ( norepinephrine)
Both adrenaline and noradrenaline having the similar functioning :
They increase the heart rate , increasing the blood pressure, increase
the metabolic rate
Hypersecretion of adrenaline or noradrenaline cause the
Hypertension, hyperglycemia, raised metabolic rate
24. Pineal gland
1. It is small body, attached to the
roof of hypothalamus
2. It is a small, pea-
shaped gland in the brain, it is
approx 10 mm long, reddish
brown in colour
3. The gland tends to atrophy
after puberty and may calcified
after that
Physiological role of pineal
gland is remains unclear
it secret the melatonin, which is
modulate the sleepiness and
regulate the body’s biological
clock
25. Sex gland (gonads)
The ovaries and testes are paired oval shaped organ referred to as
gonads
Ovaries
1. The ovaries are the female
gonads, located in the pelvic
cavity
2. They secrete the two most
important female hormone
Estrogens
Progesterone
Both hormone maintain the
female reproductive system as
well as female sexual
characteristics
The ovaries also produce the
relaxin hormone, which soften the
conncetive tissues in prepration
of child birth
26. Testes
1. The testes are the male gonads,
located in the scrotum
They secrete the most important
male hormone
Testosterone
Which is responsible for the male
sexual characteristics and by
inhibin (by Sertoli cell), it control
the sperm production
27. Pancreas
1. The pancreas is classified as
mixed organ i.e. it acts like
both exocrine and endocrine
organs
2. There are three main types of
cells in pancreatic islets (group
of pancreas cells):
• α(alpha) cell, secrete the
glucagon
• β(beta) cell are most numerous
cell, secrete the insulin
• δ (delta) cell, secrete the
somatostatin
28. The normal range of glucose level is 63-144 mg/100ml
Blood glucose levels are maintained by the opposing action of insulin
and glucagon
Glucagon increase the blood glucose level
Insulin decrease the blood glucose level
29. Insulin
1. Its main function is to lower the glucose level as well as amino acids
and fatty acids also.
2. These effect are referred as anabolic effect i.e. it promote the
storage of nutrients, when these nutrients are present in excess
amount, specifically glucose by the glycogenesis (glucose into
glycogen), insulin promote their storage immediately
Glucagon
1. Glucagon increase the blood glucose level by the process of
glycogenolysis (glycogen convert into glucose)
Somatostatin
1. Also known as growth hormone-inhibiting hormone
2. It inhibit the insulin, glucagon and growth hormone from anterior
pituitary gland
30. Thymus gland
1. Thymus gland are produced the
hormones is known as thymosin,
2. Thymosin are the hormone, which
promote the proliferation and
maturation of T cells (which is
also known as T lymphocytes
cells, responsible for phagocytises
process )
3. It maintain the immunity of the
body and retard the aging process
