Organisms that originated in a certain geographic region and can only be found in that region are said to be endemic.
Explanation:
Endemic organisms are taxonomic species (plants and animals) which originates and distributed only in specific geographic regions. This state of evolution is called endemism.
They are said to be native or indigenous to that particular region which can be an ecological habitat, an entire nation, an island, a mountain range etc. Certain parts are known for majority of their species being endemic like St. Helen Island, New Caledonia Island, Hawaiian Islands, Southern regions of Africa, and Australia.
The species becomes endemic to a particular region because of the presence of certain bio-geographical environmental qualities of that habitat which are favorable to that species.
When these conditions become unfavorable, then species becomes restricted leading to endangerment or extinction of the species.
Examples:
- Kangaroo - Australia
- Nilgiri Tahr, - Nilgiri Hills, India
- The Redwood trees of West Coast of the USA
- Plants like kalo, sumac of Hawaii
Answer:
The correct answer is- Immune system
Explanation:
There are physical, chemical and immunological barriers present in our body which helps us to protect from the foreign antigen. They all assist each other and helps in pathogen removal from our body.
The physical barrier includes skin, gastrointestinal tract, respiratory tract, etc which do not allow the microbe to enter the body. Chemical barriers include tear, saliva, acid in the stomach which kills microbes on the body surface.
Immune cells like macrophages, B cells kills microbes when it gets in the body. Lymphatic system also contain immune cells and helps in microbe removal.
So the immune system is assisted by physical barrier, chemical barrier, and lymphatic system.
One of the many tests done during urodynamic studies is the sphincter electromyelogram. This test studies activity of the voluntary muscles of the perineal area.
- Patients with urine incontinence or other symptoms of the lower urinary tract can be diagnosed with urodynamic testing.
- Both men and women take these examinations. Nerve and muscle function are measured by urodynamic testing.
- Clinically, perineal sphincter electromyography may be helpful in assessing individuals with bowel, urinary, and sexual dysfunction.
- All patients with a history and clinical examination that point to a central or peripheral sacral neuropathic lesion should be given this option.
- The pudendal nerve innervates the external sphincter (EAS), which is the best muscle for identifying neuropathic lesions in lower sacral myotomes.
