The portion of the diencephalon that acts as a relay station for sensory impulses traveling to the sensory cortex is the _______

Hitman42 [59]

Answer: Thalamus

Explanation:

The thalamus part of the brain is known as the relay station for all the sensory information. This information can be any sought of smell, light, taste et cetera.

It is relayed further via thalamus. Myelinated fiber bundle originates from the lateral surface of thalamus and it terminates at the cerebral cortex.

It is a relay station for the information from brainstem, spinal cord and cerebrum towards the cortex.

Afina-wow [57]

Answer:

a. Endomysium 8. The layer of connective tissue that surrounds an individual muscle fiber

b. Epimysium 6. The layer of connective tissue that surrounds a skeletal muscle

c. Fascia 3. Connective tissue located between adjacent muscles

d. Fascicle 12. A small bundle of muscle fibers within a muscle

e. Myosin 11. Protein found within a thick filament

f. Perimysium 4. The layer of connective tissue that separates a muscle into small bundles

g. Sarcolemma 5. The plasma membrane of a muscle fiber

h. Sarcomere 7. Unit of alternating light and dark striations between discs (lines)

i. Sarcoplasm 2. The cytoplasm of a muscle fiber

j. Sarcoplasmic reticulum 9. A cellular organelle in muscle fiber corresponding to the endoplasmic

k. Tendon 10. The cordlike part that attaches a muscle to a bone

l. Transverse (T) tubule reticulum 1. Membranous channel extending inward from muscle fiber membrane

Explanation:

A muscle has around it epimysium, which is connective tissue. Inside the epimysium, there are fascicles, and around each of them, there is perimysium. Inside every fascicle, there are muscle fibers, each of them is surrounded by a connective tissue called endomysium. Between every muscle, there is also connective tissue and is called fascia. The connective tissue has vessels and provides support.

The muscle cells are called fibers. They have a membrane, the sarcolemma, a cytoplasm, the sarcoplasm, and a sarcomere, which is the functional unit of the fiber, in other words, it is the structure responsible for the contraction. The sarcomere has different bands made of thick filaments of myosin and thin filaments of actin. They are the light and dark striations that go from disc z to disc z when we observe the sarcomere under a special microscope. The sarcoplasmic reticulum is the place that stores the calcium necessary for the contraction of the fiber, and the transverse tubule reticulum allows the contraction of various fibers since they spread the action potential amongst fibers.

Why is the influx of nitrogen not healthy for an aquatic ecosystem?

kupik [55]

The influx of nitrogen is not healthy for an aquatic ecosystem because it is not something that normally appears in that environment. It can damage the plants and animals that live in the ecosystem. It can also affect the water and soil were the plants and animals live.
