What tissue does endoderm give rise to?

Endoderm forms the epithelium—a type of tissue in which the cells are tightly linked together to form sheets—that lines the primitive gut. From this epithelial lining of the primitive gut, organs like the digestive tract, liver, pancreas, and lungs develop.

Which of the 4 tissue types are excitable?

Muscle tissue
The Four Types of Tissues Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart.

Which type of tissues are described as excitable?

Nervous and muscular tissue are both described as excitable tissue.

Which two tissues in humans are excitable?

Neurons are identified as excitable cells because they have the ability to be electrically excited resulting in the generation of action potentials. Other examples of excitable cells are skeletal, smooth, and cardiac muscle cells (Chapter 5) and secretory cells of the pancreas.

What does ectoderm give rise to?

During neurulation, ectoderm differentiates into two parts. The first is the surface ectoderm, which gives rise to tissues on the outer surface of the body like epidermis, hair, and nails. The second is the neuroectoderm, which forms the nervous system of the embryo.

What does the endoderm form quizlet?

The endoderm will form the entire epithelial lining of the gastrointestinal tract, as well as the liver, pancreas, gall bladder, thyroid, the epithelial lining of the trachea and the respiratory surface of the lungs. You just studied 4 terms!

Is epithelial tissue excitable?

Although the epithelium lacks nerves, it is excitable; electrically stimulating the epithelium initiates a propagated action potential. The average resting potential of the epithelial cells is -46 mV.

Is nervous tissue excitable?

Nervous tissue is characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body with information.

Which tissue is not excitable?

Definition: Refers to cells that do not generate action potentials. With the exception of neurons, muscle cells, and some endocrine cells, all cells in the body are non-excitable.

What tissues are excitable quizlet?

Nervous and Muscular Tissue- Excitable Tissues.

What tissues arise from ectoderm?

The tissues derived from the ectoderm are: some epithelial tissue (epidermis or outer layer of the skin, the lining for all hollow organs which have cavities open to a surface covered by epidermis), modified epidermal tissue (fingernails and toenails, hair, glands of the skin), all nerve tissue, salivary glands, and …

What does the endoderm do?

The function of the embryonic endoderm is to construct the linings of two tubes within the body. The first tube, extending throughout the length of the body, is the digestive tube. Buds from this tube form the liver, gallbladder, and pancreas.
