Question

which of the following pitches would you not expect to be able to hear (assuming you have normal hearing)?

a. 15,000 hz
b. 10,000 hz
c. 100 hz
d. 30,000 hz

provide the name (abbreviation is fine) of one of the hormones that is secreted by this endocrine gland.

Explanation:

Analyze the hearing range question

The human hearing range for a healthy young adult is typically between \(20\text{ Hz}\) and \(20,000\text{ Hz}\).

• \(15,000\text{ Hz}\), \(10,000\text{ Hz}\), and \(100\text{ Hz}\) fall within this range.
• \(30,000\text{ Hz}\) is well above the upper limit of human hearing.

Identify the endocrine gland and its hormones

The highlighted blue structure in the anatomical diagram is the pituitary gland (hypophysis), situated in the sella turcica of the sphenoid bone, connected to the hypothalamus via the infundibulum.

• The anterior pituitary secretes hormones such as Growth Hormone (GH), Thyroid-Stimulating Hormone (TSH), Adrenocorticotropic Hormone (ACTH), Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), and Prolactin (PRL).
• The posterior pituitary stores and releases Oxytocin (OXT) and Antidiuretic Hormone (ADH / vasopressin).

Answer:

Question 1

• (a) 15,000 Hz
• (b) 10,000Hz
• (c) 100Hz
• (d) 30,000Hz (Correct answer)

Question 2

GH (or ACTH, TSH, FSH, LH, PRL, ADH, Oxytocin)
