Female Reproductive System

ADULT OVARY (CORTEX) contains follicles in various stages of development, including the primordial follicle, primary follicle, secondary follicle, and Graafian follicle. Follicles are composed of an oocyte, follicular cells, and thecal cells (Table 24-1). II. CORPUS LUTEUM is a temporary endocrine gland. Its formation is dependent on A. Development. Corpus luteum develops from the granulosa cells and theca interna cells of the Graafian follicle after the secondary oocyte is ovulated through...

Lymph Node

OUTER CORTEX consists of the following A. B cells (see Chapter 9 V E), which are organized into lymphatic follicles that may contain germinal centers (these are evidence of an immune response whereby B cells are transformed into plasma cells) C. Follicular dendritic cells, which have an antigen-presenting function E. Fibroblasts (reticular cells), which secrete type III collagen (reticular fibers) that form a stromal meshwork II. INNER CORTEX (paracortex thymic-dependent zone) consists of...

Nervous Tissue

THE NEURON is the structural and functional unit of the nervous system. The neuron consists of a perikaryon cell body , dendrite, and axon, each of which contains certain ul-trastructural components Table 7-1 . The axon arises from an extension of the perikaryon called rhe axon hillock. The part of the axon between the axon hillock and the start of the myelin sheath is called the initial segment and is where the action potential is initiated. 1. Fast anterograde transport is responsible for...
