If anterior pituitary secretion is deficient in a growing child, the child will
a. Develop acromegaly
b. Become a dwarf but have fairly normal body proportions
c. Mature sexually at an earlier than normal age
d. Be in constant danger of becoming dehydrated

Verified step by step guidance

Understand the role of the anterior pituitary gland: it secretes several important hormones, including growth hormone (GH), which is crucial for normal growth in children.

Recall that a deficiency in growth hormone during childhood leads to a condition called pituitary dwarfism, characterized by short stature but with fairly normal body proportions.

Recognize that acromegaly (option a) results from excess growth hormone in adults, not deficiency in children.

Note that early sexual maturation (option c) is typically influenced by other hormones such as those from the gonads and hypothalamus, not directly by anterior pituitary deficiency.

Understand that dehydration risk (option d) is more related to hormones like antidiuretic hormone (ADH) from the posterior pituitary, not anterior pituitary secretion.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Anterior Pituitary Function

The anterior pituitary gland produces several key hormones, including growth hormone (GH), which regulates growth and development in children. Deficiency in anterior pituitary secretion often leads to impaired growth and other hormonal imbalances.

Growth Hormone Deficiency and Its Effects

A lack of growth hormone during childhood results in proportionate dwarfism, where the child is smaller than average but maintains normal body proportions. This contrasts with conditions like acromegaly, which involve excess GH and abnormal growth patterns.

Hormonal Regulation of Sexual Maturation

Sexual maturation is primarily controlled by gonadotropins from the anterior pituitary, but GH deficiency does not typically cause early sexual development. Instead, delayed or normal timing of puberty is more common in pituitary hormone deficiencies.
