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.
Secondly, ascomycota produce structures for sexual reproduction called gametangia. These structures are either male or female. The male gametangia may be anything from a detached cell (called a spermatium) to a differentiated region called an antheridium.ike basidiomycota, most ascomycota sprout from spores into hapliod mycelia. These mycelia can produce two types of reproductive structures. First, they can produce conidiophores for asexual reproduction. Conidiaphores may simply branch off from the mycelia or they may be formed in fruiting bodies.
