  1. Festinger

  2. Binet

  3. Heider

  4. None of the above

Show answer
Correct Option: A

The limbic system is formed by

zoology neural control and coordination parts of the brain brain and its parts brain

  1. The hypothalamus ,epithalamus ,amygdala and hippocampus

  2. Hypothalamus ,amygdala and hippocampus

  3. Corpora quadrigemina and hippocampus

  4. Midbrain and hindbrain

Show answer
Correct Option: A
Explanation:

the limbic system is made up of the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus.  All the components of the limbic system work together to regulate some of the brain's most important processes.

  2. Blocking N$a^+$ channels

  3. Blocking $K^+$ channels

  4. All the above

Which of the following brain structure is not considered to be part of limbic system?

zoology neural control and coordination parts of the brain brain and its parts brain

  1.  Amygdala

  2. Hippocampus

  3. Corpora quadrigemina

  4. Septal nuclei

Show answer
Correct Option: C
Explanation:
  • The limbic system is the portion of the brain that deals with three key functions: emotions, memories, and arousal (or stimulation).
  • The components of the limbic system include Amygdala, Hippocampus, Septal nuclei, thalamus, hypothalamus, basal ganglia.
  • The posterior surface of the adult midbrain is characterized by four elevations collectively called the corpora quadrigemina. It is not a part of the limbic system.
  • Hence the brain structure is not considered to be part of the limbic is Corpora quadrigemina.
  • So, the correct answer is 'Corpora quadrigemina'.

Which part of thyroid cartilage in larynx is closed?

biology control and coordination in living organisms control of blood glucose endocrine system and hormone hormones in human reproduction testes and ovary parts of the brain kidney

  1. Dorsal

  2. Ventral

  3. Anterior

  4. Posterior

Show answer
Correct Option: B
Explanation:

Larynx lies ventral to the thyroid cartilage. The thyroid cartilage is the largest of the laryngeal cartilages. The thyroid cartilage forms the bulk of the front wall of the larynx. It protects the vocal cords, which are located directly behind it.

Growth hormone is produced in

biology control and coordination in living organisms control of blood glucose endocrine system and hormone hormones in human reproduction testes and ovary parts of the brain kidney

  1. Adrenals

  2. Thyroid

  3. Pituitary

  4. Thymus

Show answer
Correct Option: C
Explanation:

Growth hormone is released into the bloodstream from the anterior pituitary gland. Growth hormone release is caused by another hormone (growth hormone-releasing hormone), which is released from the hypothalamus and it causes the pituitary gland to release the growth hormone.

Vasopressin is related with

biology control and coordination in living organisms control of blood glucose endocrine system and hormone hormones in human reproduction testes and ovary parts of the brain kidney

  1. Conservation of water

  2. Quick digestion

  3. Dilution of urine

  4. Slow heart beat

Show answer
Correct Option: A
Explanation:

Vasopressin/antidiuretic hormone (ADH) is secreted by posterior pituitary gland and targets nephron tubules to increase water reabsorption and thereby decreasing water content in urine while increasing that of blood. Increased water concentration in blood raises blood volume and blood pressure. It makes the urine concentrated. Thus, the correct answer is option A.

The follicle stimulating hormone is secreted from

biology control and coordination in living organisms control of blood glucose endocrine system and hormone hormones in human reproduction testes and ovary parts of the brain kidney

  1. Posterior lobe of pituitary gland

  2. Reproductive gland

  3. Thyroid gland

  4. Anterior lobe of pituitary gland

Show answer
Correct Option: D
Explanation:

Follicle-stimulating hormone (FSH) is a glycoprotein and gonadotropin secreted by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH) released by the hypothalamus. It helps in the development of follicles in female and triggers Sertoli cells to initiate spermatogenesis in the male.

So, the correct answer is option D.

The hyposecretion of ADH causes

  1. Diabetes melitus

  2. Diabetes insipidus

  3. Goitre

  4. None of the above

Show answer
Correct Option: B
Explanation:

Abnormal secretion of hormones brings about physical changes in the body. The hyposecretion of  ADH showcases as diabetes insipidus with increased urine output and excessive thirst. Thus, the correct answer is option B.
