Chapter 10: Basic Tissue Structure Flashcards
A group of similar cells that perform similar functions.
tissue
Science involving the study of tissues (their origin, nature and structure).
histology
__________ - is composed of two or more tissues, which perform a specific set of functions.
organ
__________ - is composed of two or more organs with similar functions.
system
___________- are the 3 layers of different types of cells, which grow and give rise to all of the body structures.
Primary germ layers
What are the three layers of cell?
ectoderm, mesoderm, and endoderm
The outer layer of the cell.
Ectoderm
The inner layer of the cell.
Endoderm
The middle layer of the cell.
mesoderm
Ectoderm gives rise to neural tube, which will fold inward and eventually give rise to the following. Except:
- Brain
- Spinal cord
- Cardiac muscles
- Retina
- Motor neurons (mostly spinal cord)
- Cranial nerves
Except: 3
__________ - arise from ectoderm, give rise to neuron of sensory organs and autonomic nerves.
Neural crest cells
Endoderm gives rise to the following. Except:
- GIT tubes (canals) and glands
- Respiratory system
- Urinary bladder
- Middle ear lining
- Circulatory sysytem
Except: 5
State if true or False:
Mesoderm gives rise to Dermatome, Sclerotome, Myotome and Sclerotome.
True
_________ - forms smooth muscles.
Dermatome
_________ - which forms to skeleton.
Sclerotome
