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.
Because of their stationary life style, fungi reproduce by forming spores, cells that are specialised for dispersal to new locations by air, water or animals. Flagellated zoospores are produced by simple aquatic fungi. Most fungi are terrestrial, growing as hyphae and producing thickâwalled nonmotile spores. Asexual spores include sporangiospores and conidia, whereas sexual spores include zygospores, ascospores and basidiospores. Ascospores and basidiospores often are forcibly ejected into the air.
