Study Notes

Types of Glands

  • Exocrine glands secrete their product through ducts.

Function of Stroma

  • The stroma provides support to the gland and allows for the delivery of oxygen and nutrients.

Classification of Glands

  • Glands are classified into two major groups: exocrine and endocrine glands.

Function of Endocrine Glands

  • Endocrine glands secrete hormones directly into the bloodstream.

Parenchyma of a Gland

  • The parenchyma of a gland is the functional part of the gland that performs secretion.

Classification of Exocrine Glands

  • Exocrine glands are classified based on their mode of secretion: merocrine, apocrine, and holocrine.

Secretion of Endocrine Glands

  • Endocrine glands secrete hormones into connective tissue.

Characteristics of Mucous and Serous Glands

  • Mucous glands have a mucous acinus with a mucin-containing secretion, while serous glands have a serous acinus with a watery secretion.

Secretions of Endocrine Glands

  • The secretions of endocrine glands are called hormones.

Mode of Secretion of Exocrine Glands

  • Exocrine glands secrete their products through ducts.

Function of Duct System

  • The duct system collects and transports the secretions of the gland to the surface.

Function of Secretory Component

  • The secretory component of unicellular glands produces and secretes the product.

Characteristics of Submandibular Salivary Gland

  • The submandibular salivary gland is a mixed gland with both mucous and serous acini.

Mode of Secretion of Sebaceous Gland

  • The sebaceous gland secretes through holocrine secretion.

Characteristics of Mucous Membrane

  • The mucous membrane is characterized by the presence of mucin, a glycoprotein.

Characteristics of Serous Glands

  • Serous glands are characterized by the presence of serous acini and a watery secretion.

Mode of Secretion of Mammary Gland

  • The mammary gland secretes lipid and protein through a merocrine mode of secretion.

Location of Goblet Cells

  • Goblet cells are primarily found in the epithelial lining of the respiratory, gastrointestinal, and female reproductive tracts.

Characteristics of Serous Glands

  • Serous glands are characterized by the presence of serous acini and a watery secretion.

Mode of Secretion of Most Exocrine Glands

  • Most exocrine glands secrete through a merocrine mode of secretion.

Characteristics of Gastric Gland

  • The gastric gland is a type of exocrine gland that secretes digestive enzymes.

Secretion of Mucous Glands

  • Mucous glands produce a mucin-containing secretion.

Characteristics of Apocrine Secretion

  • Apocrine secretion is characterized by the loss of the apical portion of the cell.

Characteristics of Serous Membrane

  • The serous membrane is characterized by the presence of a thin layer of serous fluid.
