Seeley's Anatomy and Physiology
chapter 4
Tissues - ✔️✔️Collections of specialized cells and the extracellular substances
surrounding them
Extracellular matrix - ✔️✔️Composition of the noncellular substances surrounding the
cells
Histology - ✔️✔️The microscopic study of tissues
Biopsy - ✔️✔️The process of removing tissue samples from patins surgically or with a
needle for diagnostic purposes
Autopsy - ✔️✔️An examination of the organs of a dead body to determine the cause of
death or to study the changes caused by a disease
Endoderm - ✔️✔️The inner layer of embryonic tissue
Mesoderm - ✔️✔️The middle layer of embryonic tissue
Ectoderm - ✔️✔️The outer layer of embryonic tissue
Neuroectoderm - ✔️✔️A portion of the ectoderm that becomes the nervous system in
an embryo
Neural crest cells - ✔️✔️Groups of cells that break away from the neuroectoderm
during development; they give rise to parts of the peripheral nerves, skin pigment, the
medulla of the adrenal gland and many tissues of the face
Epithelial tissue - ✔️✔️Covers and protects surfaces. Is mostly composed of cells,
covers body surfaces, distinct cell surfaces, has cell and matrix connections, is
nonvascular, and is capable of regeneration
Functions of epithelial tissue - ✔️✔️Protecting underlying structures, acting as a
barrier, permitting the passage of substances, secreting substances, and absorbing
substances
Simple epithelium - ✔️✔️Consists of a single layer of cells, with each cell extending
from the basement membrane to the free surface
