Falls are the most common cause of traumatic brain injury, and falling poses an especially serious risk for older adults. When a senior sustains a traumatic brain injury in a fall, direct effects of the injury may result in long-term cognitive changes, reduced ability to function and changes in emotional health.
Asexual reproduction is by means of spores produced in sporangia borne on the hyphae. Zygomycota get their name from the production of thick-walled sexual structures called zygosporangia, which can remain dormant for long periods.
The Ascomycetes are fungi that produce their spores in little tubes called asci (the singular is ascus). The tubes are located on the spore-bearing surface of the mushroom. Thousands and thousands of fungi belong to the Ascomycetes, but most of them are not mushrooms as we mushroom hunters think of them.
