What are the two types of tissue repair?
The two types of tissue repair are regeneration, where damaged tissue is replaced with new functional tissue, and fibrosis, where damaged tissue is replaced with scar tissue made of collagen fibers. Regeneration is ideal as it restores normal tissue function, while fibrosis can lead to loss of function depending on the extent of scarring.
What tissue are in the nervous system?
the brain,spinal cord and the nerves
Which two of the basic kinds of tissues cannot be regenerated if injured?
Nervous tissue and cardiac muscle tissue are two types of tissues that have limited capacity for regeneration. Injuries to these tissues can often lead to permanent damage or scarring, making it difficult for them to fully recover.
Cell type found in nervous tissue?
The main cell type found in nervous tissue is the neuron. Neurons are responsible for transmitting electrical signals within the nervous system and are specialized for communication through both electrical and chemical signals.
What are two tissues that is replaced largerly with scar tissue?
Two types of tissues that are largely replaced by scar tissue are cardiac muscle tissue and nervous tissue. In the heart, after a myocardial infarction (heart attack), damaged cardiac muscle is replaced by fibrous scar tissue, which does not contract or function like healthy muscle. Similarly, in the nervous system, injuries to neurons often result in scar tissue formation by glial cells, which inhibits regeneration and functional recovery.
What body tissue transmits electrochemical impulses?
Nervous tissues are notorious for conducting the electrical as well as chemical impulses. The later occurring at synapsis which is the cleft between the connection of two nerve endings. Also heart cells can conduct electrochemical impulses.
General characteristics of nervous tissue?
There are several characteristics of nervous tissue that make them easy to identify. Nervous tissue is made of many cells packed closely together, and most are strongly branching. There are two main groups of cells: the neurons, and the glial cells. You will find nervous tissue in the brain and spinal cord, and in the nerves and their associated ganglia. Nervous tissue is the main component of the nervous system, which regulates and controls body functions.
What are specialized cells that do all the support activities for the nervous system?
Neuroglia are the supporting cells of the NS. There are four types in the central nervous system (CNS) and two types in the peripheral nervous system (PNS). They all have functions that contribute to the overall health of neuron cells.
Describe the protective structures and the gross anatomical features of the spinal cord?
two types of connective tissue coverings - bony vertebrae and tough, connective tissue meninges - plus a cushion of cerebrospinal fluid surround and protect the delicate nervous tissue of the spinal cord.
What are the two types of peripheral nervous system?
The two types of peripheral nervous system are the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary bodily functions like heart rate and digestion.
What do you call two or more tissues together form?
Two or more tissues together form an organ. Organs are structures that perform specific functions within an organism and are composed of various types of tissues working collaboratively. For example, the heart is an organ made up of muscle tissue, connective tissue, and nervous tissue.
What is the difference between muscle and nervous tissue?
Nervous tissue is composed of nerves containing neurons, specialized cells. Muscle tissue contains myocytes, which have completely different structure than neurons. Also, muscle is organized in many fibers covered by connective tissue; these fibers build up stronger fibers etc. Neural tissue has different organization.
