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.
Basidiomycota (club fungi): Basidiomycetes also possess septate hyphae. The sexual spores, called basidiospores, are produced by a club-shaped structure called a basidium. In mushrooms the basidia are found along the gills or pores on the underside of the cap. Some mushrooms produce toxins that are lethal to humans.
