How do the Merocrine apocrine and Holocrine secretions differ?
How do the processes of merocrine, apocrine, and holocrine secretion differ? Merocrine and apocrine secretions leave the cell intact and are able to continie secreting; holocrine secretion does not. What three basic components are found in all connective tissues?
Which tissue type is formed Embryonically by many stem cells joining together?
Embryonic Connective Tissue All connective tissues derive from the mesodermal layer of the embryo (see Figure 4.2. 2). The first connective tissue to develop in the embryo is mesenchyme, the stem cell line from which all connective tissues are later derived.
What is true about connective tissue?
Connective tissue is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. It develops from the mesoderm. Connective tissue is found in between other tissues everywhere in the body, including the nervous system.
What is the name of the tissue which helps in protection and support of the body?
Epithelial tissues act as coverings, controlling the movement of materials across their surface. Connective tissue binds the various parts of the body together, providing support and protection.
How do merocrine apocrine and holocrine secretions differ quizlet?
How do the processes of merocrine, apocrine, and holocrine secretion differ? Merocrine- the product is released through exocytosis. Apocrine- loss of cytoplasm as well as the secretory product. Holocrine- product is released, cells destroyed.
What is the difference between apocrine and merocrine?
The key difference between merocrine and apocrine sweat glands is that merocrine sweat glands excrete sweat directly onto the surface of the skin opening out through the sweat pore while apocrine sweat glands secrete sweat into the pilary canal of the hair follicle without opening directly onto the surface of the skin.
Which muscle tissue type is formed by many cells joining together which are Multinucleated?
Because skeletal muscle fibers have obvious bands called striations that can be observed under a microscope, it is also called striated muscle. Note that skeletal muscle cells are multinucleate, that is, each cell has more than one nucleus.
What are the cells and cell fragments of blood collectively referred to as?
Cells and cell fragments of blood are collectively called the formed elements of blood. The extracellular matrix of blood is called plasma and is a composition of water, blood proteins and all inorganic and organic substances the blood carries.
What are the roles of the connective tissues in the body?
Tissue that supports, protects, and gives structure to other tissues and organs in the body. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue. Connective tissue is made up of cells, fibers, and a gel-like substance.
What is the role of connective tissue?
Connective tissues bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage.
Which tissue type is responsible for movement body heat production and protection of organs?
Because the muscles are under our conscious control, they are considered voluntary muscles. Functionally, they contribute to the shape, motion, posture, heat production and protection of the body. is found throughout the internal organs of the body, particularly in the digestive tract.
Which tissue helps in movement of the body?
Skeletal muscle tissue consists of elongated muscle cells called muscle fibers, and is responsible for movements of the body.
