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.
Sporangia are formed at the end of aerial hyphae called sporangiophores. Rhizopus. Fungi are taxonomically classified according to the type of sexual spore that they form, but clinically, since most only exhibit asexual spores in the lab, are classified by asexual spore type. Sexual spores are usually produced in response to special circumstances, often changes in the environment.
